The steps to build an... E-Car The chassis The Axles The Wheels The Motor The Motor Mount The Battery Pack The Battery Clip is the object required to transfer electricity to the engine from the battery. It is connected to the front of the Battery Pack (7th Slide) and there are certain red wires connected to it to conduct the electricity to the
Motor(5th Slide) The Battery Clip The L-Bracket(Left Picture) and Switch are there to help turn the vehicle's electric motor(5th Slide) on and off. If this was not put on the vehicle, the motor would stay on all the time and the vehicle would stay on all the
time until it ran out of energy and shut off by
default.This is on the vehicle to stop it on
command and conserve energy. L-Bracket and Switch The chassis was built on SolidWorks and is the main body and structure that holds all the essential pieces together. This part is also required to have some holes to hold some mounts and other accessories. This needed to be extruded
and cut to make holes for the
main accessory holsters The axles are the parts needed to hold the wheels on. They fit into the holes into the sides of the Chassis. When that is done, the Wheels(4th Slide) are fitted onto the ends of the axles to let the vehicle
move. The rear axle(Left picture) is a bit
larger than the front axle
(Right Picture). There are three types of wheels on this car, one wide for the back(Right picture), another rear wheel but grooved(Left Picture), and a thin wheel(Middle Picture) to give greater turning results in the
front. The grooved wheel(Left picture)
is for the rubber band to fit in
it to make it spin. The Motor is the engine of the vehicle,
it's an electric motor so it's powered by
batteries.This motor moves a rubber band
which powers the Wheels(4th Slide). (Model Size) The Motor Mount is the part of the car that attaches to the chassis and holds the
Engine/Motor(5th Slide) in place for the car. It's very
necessary to hold the engine in an exact spot so
the wheels run correctly and don't make the
vehicle turn incorrectly The battery pack is the main and only power source for the E-Car and it's other accessories. Without
this part of the E-Car, the motor would not work
and the car would not move. There are many reasons why Technology engineering is awesome! The Reasons Why Technological Engineering is Awesome! First off, It's extremely well paying and can be a lot of fun! The things that can be built are endless! It's also a great source of knowledge when learning about physics, particles, why things fly on Earth and why they don't on the Moon. How things can actually be flown on the Moon and if it actually will stay in orbit or not! The Design Squad Questions The Pulley and Rubber Band The Slot Wood Block(Left) and Slot Wood(Right) are there to help the E-Car run on tracks and help to control it. There are certain tracks required to have the E-Car stay on the track. The Slot Wood Block is there to help the Slot Wood stay in place. You push the
Slot Wood through the slit in the E-Car to help the Vehicle
to stay on track. Without these parts of the vehicle,
the E-Car would run off the track! Slot Wood and Slot Wood Block Braided Wire is On the bottom rear of the E-Car to brush against the track the E-Car is on. It is very necessary for the E-Car to stay in one direction. These Braided Wires help the vehicle's traction immensely.
They are made of Wire, as the name states, to run it on any track and
help it stay on course. Without this, the E-Car would most likely
Run all over the place and go completely out of control. These
are very necessary to also help the E-Car do as you please
and keep it from running off the road and crashing.
There is also two of the Braided Wire, they are
put side by side on the rear end of
the E-Car Braided Wire The Bolts are the part of the E-Car that holds all the parts and accessories on, these bolts are necessary to have the E-Car stay together and not fall apart during a test-drive or during examination. Without these the E-Car would not work at all and everything
would be a giant mess. The Bolts The Pulley(Left) is the part of the chassis that lets' the Rubber Band(Right) Spin and stay in place. The rubber band is connected to the Groove of the Rear Wheel in the right picture. This groove also helps the Rubber
Band stay in place and not go everywhere.
The Rubber Band also has to have some
friction, so it is made out of
rubber. The Final Product The E-Car is Almost Ready to Roll! The E-Car is now a finished product! The E-Car is now very close to a full working product, all
that is needed now is to hook up wires
from the battery to the motor.
Then the car is ready! What the X, Y, and Z axis are and how they work The X, Y, and Z Axis The X, Y and Z axis are types of coordinates, they are part of the Cartesian coordinate system. This coordinate system is used for countless projects and measurements. The X is Length, the Y is Width, and the Z is for Height. The coordinates take a big role in math also.
The coordinates have also been used this year in the making of the E-Car. The E-Car required a big knowledge of coordinates to line up certain objects to the E-Car. The program, "SolidWorks", just like any other modeling program requires coordinates and measurements to precisely build the E-Car. Only the X and Y dimensions are required to Create a two-dimensional drawing or object; thus, the word two-dimensional. If Z, the third dimension, is added it is a three-dimensional object. Three-Dimensional objects are objects with height, length and width! The Objective of the Competition is to help the competitors realize how important convenient, clean drinking water is. It is also to allow the participants to create innovative and original ideas to and to help inspire students to create and become great water professionals. What is the Objective of Competition? Water Tower
Competition The Judging Will be based on four main groups How is it Judged? Hydraulic Efficiency
Cost Efficiency
Structural Efficiency
Design ingenuity It is to use convenient and available resources without buying and using to much money and only being efficient by mostly using recycled products and not having bought everything. What is Structural Efficiency? It is the amount of water that is flowed out of the tank through a tube in a certain time. We want to make the water tower specifically to drain water from the tank fast enough to get the water out of the tank and somewhere else quickly, and efficiently. What is Hydraulic Efficiency? What is Cost Efficiency? The structure of the Water Tower must be light, convenient and firm, without these factors, the Tower would most likely fall apart, be very hard to pick up, and make a enormous mess on the testing area. What are the Penalties? The Design of the Water tower should be original and include great Hydraulic efficiency, Structural efficiency, and great Cost efficiency. In other words the tower should be light, strong, cheap, mobile, and cheap! Explain Design Ingenuity These are the following penalties Must fit in a square with 1 ft on each side
Tank must be between 1.5-2.5 ft high
Must have removable lid so air can escape
Tank must hold 1-2.5 gallons of water
No leaks
Must use 3/8 inch connector(Supplied)
Bring Receipts for all products
Bring List of Materials
Must Be designed and built for this year's competition What is the Weight of 2.5 Gallons of Water? The weight of 2.5 gallons weighs: 20.8 Pounds Water weight relates to structural efficiency because the Structure has to hold the water's weight combined with it's own weight to not collapse and work How Water Weight Relates to Structural Efficiency How much water would the average water tower hold in pounds? Prezi Post 10/5 1,456,000 Pounds This water tower has the viability to evolve into a greater water tower by using stronger, light weight materials for easy transport. This water tower also has desirability because of light weight, yet strong materials for good structure of the water tower. The desirability also increases when the materials are recycled and are very cheap. The value of the water tower can also depend on how well the tower works and how cheap it costs. The desirability of the water tower can also increase with these stats. This water tower can also be capable by being able to transport water from the tank. This water tower is also capable because it can be transported or held and still not collapse. This water tower can have plenty of value when it is improved to fit these specifications and goals. These goals are also how to make my water tower innovative. How this Tower can be Innovative Using:
Desirability,
Capability,
and Viability Post 10/19 An elastic collision is when two bodies of mass encounter one another physically in which the kinetic mass of the bodies after the impact of one another is still equal to their kinetic mass before the impact/encounter. This can be compared between two bats, one wooden, and one aluminum. When a baseball hits the wooden bat, it only goes a distance of around 400 feet from an average baseball player. When the aluminum bat is used, it gets around 550 feet of distance from the point of impact. This is because the baseball hitting the wooden bat means that the baseball loses more kinetic energy than when it hits the aluminum bat. the reason for losing more kinetic energy is because the wooden bat absorbs more of the impact from the baseball than an aluminum bat. for an example, if the swinger of the bat used a pillow for a bat, the pillow would absorb the ball's impact and the ball wouldn't go anywhere but downwards. The ball's momentum and kinetic energy is used to deform the bat and the bat takes the impact because wood is more weak than aluminum. When the player uses an extremely strong aluminum bat, the ball would try to dent the bat, but the elastic collision of the atoms between the two bats would send the ball flying and the bat would only have a scratch on it. Elastic Collisions Prezi Post 10/26 Water Tower Score Card This is the score card for the current water tower this year Steps to build a... C02 Dragster (Fast and Furious) Prezi Post 11/9 How do wind tunnels simulate flight? Wind tunnels simulate flight by spreading air all around the chassis of the vehicle. Wind tunnels can also be compared to flight because of being pushed through air. These simulations can also be compared to wind tunnels in the fact that the aerodynamics are almost carrying the chassis of whatever vehicle because of lift, or pushing it down because of the slant of the vehicle's front. Wind tunnels can also simulate flight because of the air being pushed through the chamber that the vehicle is being tested in. These wind tunnels can also simulate flight by helping push the vehicle into the air and send it flying, technically speaking. Also, the wind tunnels. Also, the forces acting on the chassis of whatever vehicle is being used is almost exact to those when used in flight. These simulations are also not only used to help with aircraft, but with many other means transportation. Just like it is said in the last sentence, all types and forms of cars, boats, and other things(motorcycles, scooters, etc.) are used in wind tunnels not only to test the aerodynamics of the vehicle but to somewhat simulate flight. The Normal Chassis This is the Regular chassis, this chassis has the axle holes and wheel slots.
This is the main chassis that holds all the Wheels and axles together.
This chassis is also the base or stock version of the future chassis that
has not been carved yet or modified in any way other than the axle
slots or wheel placements. The aerodynamics of this version of
the chassis are very bad and the flow of air around the
vehicle is extremely poor creating much drag thus,
making the vehicle slower. The Cut and Improved
Chassis This version of the Shell car's chassis is much improved from the last version and has much less drag. This
chassis is also more compact and lightweight. The
car still has the capability of holding all the
required accessories that the vehicle needs to
move. This chassis also has a bit more
aerodynamics on the sides to let
the vehicle cut through
the air Mike Rowe and the Skills Gap Prezi Post 11/16 "The skills gap seems real and is getting larger." The Skills Gap is the gap of jobs between
low maintenance jobs and high maintenance jobs. If we can close this gap and create well-paying jobs for plenty
of people, then so
many other people
will be employed and
happy. The Front and Rear Wheels The Wheels are the main support for the Dragster and keep it from scraping and touching the
track.These parts are extremely important
for the Dragster's mobile ability, without
them, the Dragster would move at maybe
half it's speed and also fly off the track
because the Wheels are providers of
the car's main traction.
These were extruded
and cut (Front) (Rear) Front and Rear Axles The Front and Rear axles are the main supports for the wheels and are attached using mates to easily slide into place. These
are very important to be easily moved yet
stay in place to help the wheels move
and for the car's sake to because
the wheels let the car move
smoothly. (A Pagani Zonda in a wind tunnel) The Front and Rear Spacers These Spacers have been cut by the extruded cut tool and have been extruded cut tool to fit in between the two front wheels and the two back wheels these spacers space the
wheels apart to help the wheels' spin rate and maximize
the C02 Dragster's full speed. These spacers have also
been mated to the axles to maximize ease and
performance for the car overall. Also, the
wheels without the spacers would
rub against each other
and damage the car. Welcome to My Prezi! l (The extruded and mirrored pulley) (The pulley mated to the rubber band and motor) (The slot wood block was filleted for better aerodynamics on the E-Car) (The slot wood was also extruded to increase its sturdiness and filleted to help control on the E-Car's track) The braided wire has
been extruded to
increase its traction
and road resistance These bolts have been imported from the bolt explorer to keep the E-Car together These axles have been created using the circle tool and smart dimension and have also been extruded to make a physical affect on the car These two types of back
wheels have been filleted
and extruded to
help the car's traction The front Wheel hasn't been as
extruded as the two back wheels
so that the front wheel has a better
turning rate This motor has another extruded sketch on its right face so that it can run the E-Car This mount has some square fillets and has been mirrored for simple use. The battery pack has a sketch on its face consisting of two circles, one extruded and one with an inverted cut. The clip has first been mirrored and extruded and filleted to increase usability and has a sketch consisting of the two circles, one inverted and one normally extruded This bracket and switch have
both been sketched, filleted,
and extruded to help usability
of the E-Car This chassis has
been used necessarily
with the fillet tool to
increase aerodynamics
immensely This base of the
chassis is extruded
and is cut for use
of the axles. These axles have been extruded at different lengths to comfortably fit the car. These parts have also been filleted at the sides so the aerodynamics of the parts are enhanced. (Rear) (Front) These spacers weren't filleted
because if the spacers were, they wouldn't space apart the wheels very well The Washer This part has been cut through the middle to be mated onto the axle. It has also been extruded to have a physical effect on the Shell Car. The Washer is used to keep the Shell Car's wheel slot clean and to help keep it working fine. This can be very important for future uses and to help the car' overall sturdiness. Without this, the wheel slot would be trashed and the wheels would scrape against the side of the
wheel slot and probably wreck the
car and not to mention it
would slow the shell
car down. The Assembly Parts have been
inserted and
mated to ease the construction
of the Shell car.
This file is also an assembly file so the body can be assembled with ease. This is the Shell Car Assembly, the picture(above) is showing what my Shell Car will look like. The body has been used to almost entirety. The Assembly contains
2 front wheels, 2 rear wheels, the front and back
axles, a washer in the back wheel slot, a front
spacer in between the two front wheels, and
a rear spacer in between the 2 rear
wheels. The Eye Screw The Eye Screw is for a fishing line to fit through.
That fishing line is what keeps the Shell Car on the track. Without this screw, the fishing line wouldn't go anywhere, and the shell car would
literally fly off the track and crash. The
fishing line is necessary to prevent
damage to everything,
including the
car. The Eye screw has been revolved with the revolved boss/base
tool. The Screw has also been majorly filleted to have the "screw", or drilling part of the screw actually drill into the Shell Car and stay in place. (Rear Screw Location) (Front Screw Location) The CO2 Cartridge The Shell Car's Main source of thrust is the CO2 Cartridge. This will send the Shell Car up to speeds of around 60 mph! The CO2
Cartridge is snugly fit into the area in the back of the Shell Car.
Without this, the Shell Car wouldn't be able to move at all
without any help from other forces. The Cartridge is full of
compressed CO2 and when the cap is removed, all the
CO2 explodes out of the car creating an insane
amount of thrust for the tiny shell car. When
the cap is removed, it's going to send
the car through two rooms
in under a second. This Cartridge has been filleted and mated with the Shell Car's back slot to fit into the Shell Car's tightly. The Final Shell Car The Shell Car has been rendered to give it a nice, glossy shine This is the Final Rendering of the Shell Car and has been manipulated to it's full potential. The glossiness is from rendering it in SolidWorks, the program used to render the vehicle. This shell car won't look
exactly like this when printed through the
drill but can still be painted and look
almost exactly like this. All parts
are attached to this version of
the Shell Car. Shell Car Flow Simulation This is the Flow Simulation of the Final Shell Car and was created using SolidWorks' Flow Simulation Program. This Flow Simulation is the flow simulation of the final Shell car with all parts attached to the chassis. The outcome has told me I've reached my goal and
that this Shell Car is efficient enough to
compete with the other Shell Cars in a
competition. This competition tests
all the aerodynamics of all the
Shell Cars by shooting them
down a track and recording
the time. Prezi Post 11/30 What are the lowest and highest salaries for a SolidWorks career? The Lowest Salary on monster.com is: $12/hour

The Drawing was created by using SolidWorks' Drawing program. Prezi Post 12/14 CNC (Computer Numerical Control) This is the process of controlling machines through applications of other circuitry and computers. This can really provide an advantage over other techniques because of its extremely flexible and varied uses. The machines that have movements which are controlled by screws, levers, wedges, and other mechanisms are then guided by digital computers for added precision. Semester Exam Part This random part was required to be created in the program SolidWorks to pass the course's semester exam.
