Business Card
This is an example of a business card
that this class created in Corel Draw.
Corel Draw honestly is a pretty hard tool to work with. In many student's opinion, the written tutorial was very complicated. This business card project will help other's careers in the future at least having a building block of Corel Draw and an understanding of laser-engraving.

What is Career and Technical Education?
According to acteonline.org Career and Technical Education or CTE for short, is a “Cutting-edge program that prepares youth and adults for a wide range of high-wage, high-skill, (refer to the diagram in the top right corner) and high-demand careers. The average graduation rate concentrating in CTE programs is 90.18 percent compared to the national average of freshman at 74.9 percent. CTE gets people ready for multiple careers in tech-related areas, because adults with CTE-related associates degrees and/or credentials make (on average) between $4,000 and $19,000. CTE not only benefits those who follow a career path in that area, but it assists state economies as well. In Washington for every dollar invested in CTE, the state earns $9 in revenues and benefits. CTE as one might imagine is beneficiary to business, with many graduates with history using CTE. STEM occupations like environmental engineering and science technicians require an associate degree and will experience faster job growth in the particular areas. CTE servers 94 percent of all high school students no matter race (ethnicities too), gender, or income backgrounds. In 2002, 88 percent of high schools offered at least one CTE program, with many being assisted by career centers-- 1,200 in 41 states in 2002.
This year is the 11th annual Model Water Tower Contest. As any competition does, this one has quite a set of areas to be judged. In these set of areas, there's four different things to keep track of.
1) Structural Efficiency
Every single multiple-story building would just fall over without a base, or structure. This area judges on the assistance the structure gives on a water tower.
2) Hydraulic Efficiency
What use does a water tower have if it can't drain quickly and correctly? This area judges the water tower on it's hydraulic efficiency, or the water speed draining.
4) Design Ingenuity
If the state of Florida were to build a water
tower right off the highway without applying
a good set of paint or just leaving it without a
theme doesn't look nice at all, does it? It most
likely would give tourists a funny feeling.
3) Cost Efficiency
As any state looking to build a mew water tower, they do not want to spend much money on it. This area the judges will decide how many points you get (points are bad and costly towers are worse towers) towards the final score.
Penalties:

1) The base of the water tower must fit into a square
foot, in either a circle or square.

2) The tank has to be between 1.5 and 2.5 feet tall

3) The tower must have a vent or lid so the judges can tell whether the tower is full or not.

4) The tank to the water tower must hold 1 to 2.5 gallons of water (1 point if it holds less) and no advantage if it holds more.

5) Like any water tower, it should
NEVER
leak, and it would even help to test it out and find out how much the water weighs at full capacity.

6) The tower must have the space for the 3/8 connector, and the connector
MUST
be installed in the base of the tower.

7) You must bring a receipt for all items purchased used in the process of building, and all items purchased without a receipt shown will get a point penalty. (Maximum of 3 points penalty)

8)
Bring
a list of all materials used! 3 points will be added for a list not supplied.

9) Models
MUST
be designed and built for this year's competition
ONLY
from this year, and you may not re-enter models from previous years.
Water towers are highly important to the homes and businesses around them. Water towers are so important, they play the key role in getting water to our homes. A lot of water towers are tall, and that does more than you think. A water tower gets the water back down to the ground by using pressure and each foot of height a tower has, it adds 0.43 PSI.
2.5 gallons of water weighs 8.33lbs. Now just imagine that times 5,000! Then you would get an idea of how much weight an ordinary water tower holds.
How can technologies help repair damage caused by natural disasters?
Technologies such as helicopters can be a major help in repairing damage caused by natural disasters. Referring to the diagram, helicopters can fly in over debris not accessible through Jeep® for instance, and those equipped with a minor crane of some sort can shift debris aside (fallen trees, toppled power lines, etc.) out of the way and open the roads for disaster relief crews. Even technologies like phones can help repair emotional damage, after all there's nothing more comforting than knowing those close by are safe and sound. In the aftermath of natural disasters buildings (homes, businesses, schools, etc.) are destroyed. When these buildings are nearly obliterated, it causes a heavy amount of debris to be cast even for miles around the area; something as simple as a bulldozer can move the debris to city dumps for instance and clear the way for construction crews or anyone else needed in natural disaster relief. Chainsaws are even useful in
disaster relief. They can be used to cut debris down to size
and split toppled trees so others can get through too. In
the aftermath of natural disasters, buildings are destroyed
(look above). This may seem a little far-fetched, but I think
SolidWorks could be used in the reconstruction of the
buildings destroyed.
The three dimensional coordinate system consists of an X axis, a Y axis, and a Z axis. Referring to the diagram, when adding the Z axis to a normal X and Y plot graph, it gains 3D properties. In the diagram, the dot at the center of all three axes is referred to as the origin, where all three axes connect. In laser engraving machines, the way it can engrave letters, symbols, etc. that path it follows is the X and Y axes. A 3D laser engraver by using the Z axis can engrave objects providing depth and a professional look. More often than not, laser engravers can make 3D designs by using the X, Y, and Z axes, referring to the diagram in the lower left hand corner. Laser engravers that incorperate the X Y Z axes can go for about $7,500+ U.S. dollars. In the diagram located directly in the bottom middle, is an example of what a 3D laser engraver looks like. The white bar on the side of the laser bar can rise and lower, making the Z axis engravable.

First Electric Motor Research Post
Source:
"Electric Motor." Wikipedia. Wikimedia Foundation, 10 Sept. 2013. Web. 10 Oct. 2013
The first electric motor is believed to have been created in the 1740s (according to wikipedia.org) by the Scottish Monk Andrew Gordon. The motor was merely a simple electrostatic device capable of producing mechanical force through the interactions of an electric current and a magnetic field. Ányos Jedlik's DC motor (the graphic in the lower right hand corner) is an electromagnetic self-rotor and surprisingly, still works perfectly today. Using the same principle of the original motor, Ányos created a toy car that derived it's power from the electromagnetic self-rotor. In 1886 a man named Frank Julian Sprague invented the very first practical DC motor. The motor was a non-sparking one that could maintain (relatively) constant speed under different load weights. Frank Julian Sprague's other electric inventions around this time had massively improved grid electric distribution, prior to Thomas Edison's work. (Cited from en.wikipedia.org/wiki/Electric_motor)

Water

Rocket
Velocity Equation
"What Is a Water Rocket?"
Water-rockets Science for Hobbyist, Students, and Teachers of All Ages.
N.p., n.d. Web. 14 Nov. 2013.
A water rocket is a rocket powered by pressurized water. A water rocket primarily works through a portion of CO2 (Carbon Dioxide) forcing down upon water. As the water is a Neutonian fluid, the CO2 pushes the water out quickly. As the bottom of the rocket is released, the CO2 forces the water out of the rocket, causing it to blast into the air; the equation for the rocket's velocity is in the lower left corner. Contributing to getting a water rocket into the air however, is an unrecognized part of the equation: aerodynamics. Like in the diagram in the upper right corner, a
equation: aerodynamics. Like in the diagram in the upper right corner, a contributing factor are the wings.

suspension cables, the world of bridge design is constantly changing. Back before the 1960s, all that was used was truss bridges (refer to upper graphic). Although, with new centuries come new ideas, suspension cables are in use. A great example of this is the Sunshine Skyway Bridge; it has been demolished a few times for reconstruction, but it has prevailed since

Week's Progress

(Week of 12/2)

This week has been highly beneficial to the in-progress

Career Prep entry being worked on. The résumé is already completely done. The graphic in the lower left corner is just a snip of what was done; there's a whole page of it. Next week the cover letter will be accomplished, and the entry will be complete.

process, bridge
design has changed
most, and definitely is
crucial.

Critical Load
A "Critical Load" is the load when a bridge support is most likely to fail. This is most common on bridges with common traffic. With the average car weighing in at 3,846 lbs., bridge support is crucial; usually saving thousands of lives a year.

Week's Progress
(Week of 12/9)
This week the entire Career Prep entry for
TSA
has been completed. The entire process took about one (1) school week. It has yet to
be submitted. For the event, the participant had to complete and turn in a
résumé
and a
cover letter
. Honestly the cover letter was harder, being that you had to research a Game Programming company and then "write" to the company stating that you're the right position for the "job" and why.

Here's a scenario: While in the International Space Station, a piece breaks off. Rather than wait for a few months for the next supply rocket, what can be done? The answer is 3D Printers. With these such tools in space, America can spend less money

on fuel for the supply rockets. Of course, these things in space can look pretty cool, but that doesn't matter; these 3D Printers could eventually save
lives
. This Printer is just starting off by printing plastic, but NASA has announced that metal will be used in the near future.
With technology like this in space, the possibilies are countless. Maybe with the extra money from saving rocket fuel we can lower the national debt? Just an interesting thought to chew on.

This week's work mainy consisted of working on the TSA event, Water Infrastructure. As seen in the lower right-hand corner, the binder has been put into
Google Docs
and is nearly finished. With this work, (and the SolidWorks part in the lower left-hand corner) this project will definitely make it to the State Conference.

The first steam turbine engine

was invented in the late

19th century by a well-known Swedish engineer named
Carl Gustav de Laval
, and along with it, invented the
de Laval nozzle
(or
con-di nozzle
)
.
This nozzle was built to maximize the speed of the steam hitting the blades of the turbine. Robert Goddard used these nozzles when building rockets, popularizing them today.
Lean Manufacturing is the process of placing small stockpiles of inventory in specific places around an assembly line, eventually becoming more efficient as humans would not need to retrieve a large load from a centralized warehouse, therefore allowing robotic arms to cut down the time because they can just lean over and pick up the necessary supplies. This not only reduces waste, (carbon dioxide released by trucks and shipments of necessary supplies from an offshore warehouse) but it increases the productivity of the warehouse floor.

Gear Ratio
A gear ratio is the ratio of angular speed of the very first gear in a gear train to the very last gear in the gear train. Gears change the way force is applied in speed because of their position in the gear train and how fast the gear next to it is going.
