Transcript: Advantages Disadvantages Complicated Needs an ESC to operate Expensive Intricate Wiring Difficult to do maintenance on Operates effectively at all speeds. High efficiency/power size ratio; Smaller Superior thermal characteristics Lower noise level (due to the absence of a commutative plan) A brushless DC electric motor, is a synchronous motors powered by DC electricity from a switching power supply. (But how do they work?) FIN (But how do they work?) A brushed electric motor is an electric motor designed to be run from a Direct Current power source. Brushed motors have been used for more than 100 years. My Thoughts What is a Brushed Motor? Most of you probably aren't interested in this subject; but I am so deal with it!

Transcript: Bad Breath How were teeth brushed? Poor people had the option to sell their teeth for money and their teeth were used in people's need for teeth People who would need teeth would purchase human teeth and when human teeth aren't available, they used animal teeth.

Transcript: Things we do Blacksmiths make things like fireplace tools and normal tools. Normal tools would include things like Wrenches, Pliers, and Screwdrivers. Don't think that's all because we also make everyday metal things such as hammers and horseshoes. Forging- is the process where the metal is shaped. Metal to Metal We chose here because this was New Amsterdam first wharf. (A wharf is a level quayside area which a ship may be moored to load and unload things and people.) Where do we get our materials? Thank You for watching this slide show. For your enjoyment please enjoy this video of a blacksmith juggling some hammers. Upsetting- makes metal thicker. What are we asking for? Any weather is fine except for severe weather and snow. The Life of a Blacksmith Weather needed Anvils (which is a heavy steel or iron block a flat top,concave sides and typically a pointed end which then you hammer and shape stuff on the anvil. Hammers ( a common tool that is used to bang things. Tongs (a instrument which has two moveable arms that are joined at one end for picking up and holding things. Vise (a metal tool with movable jaws that hold things firmly in place while work is done on other things . A file ( a pole like think that is flat based and has scrape lines so you can sharpen or flaten things. The blacksmiths lived in Dutch settlements during the time of 1703. Welding- to join the same or similar kind of metal. Charcoal: Charcoal is a amorphous form of coal obtained as a residue when wood, bone, or other organic matter is heated in the absence of air.

Finishing- to paint, varnish, oil, and wax. Bending- heating the metal to where it turns red so that you can bend it. What was the yearly salary for a blacksmith in the 1700's? Combining- is to combine all of your parts to make one thing. Depending on the cost of each steel rod which is 130 shillings and we are trying to get to 48,000 shillings to make us an international business. We need a total of 2,900 shillings for 30% of share. 8 Things we do. Budgeting and Pricing Where did blacksmith's live? By: Tyler, Mathew, and Mitchell We are based at the Schreyers Hook Dock in New York City. Materials we use What tools do you need to be a blacksmith? Drawing- lengthens the metal by reducing one or both of the other two dimensions. Associated Businesses Needed Procedures We get all of our metal to work with from a steel yard. What's a steelyard you might ask? A steelyard is a huge workshop full of different sorts of metal poles. Why did we choose here? Things we make Punching- creates a decorative pattern or to make a hole. These are the types of weather that you don't want to do it in. Where are we based? The shelter should be stone and it should have a big rectangular opening. This is mainly because it needs air for the smoke to circulate through.
Transcript: this is what a traxxas e- revo looks like. the traxxas e-revo brushed version is an electric truggy that's ment for racing. what i mean by brushed is that there are brushes in the motor which is of course electric that kind of sweep the motor while you're driving. the brushes are just soldered on. a truggy is a low cg monster truck, and cg means centre of gravity. your centre of gravity as basically your height of the chassis. the traxxas e-revo takes 2 7-cell stick-type batteries. they look like this. ok, so this prezi will be about the traxxas e-revo, brushed version. here is a demo video to show you just how fast this thing is. the chassis is what holds all the elctronics and battery /batteries securely.
