Why Did We Choose These Materials?

To create a mousetrap car and measure its performance. We will also see where force and energy is impacting on the performance, for example friction will impact on the cars performance as it generates heat and slows to car down thus meaning that the car may not travel as far as it should. Another force that is demonstrated in testing of the car kinetic energy, without kinetic energy the car would not travel at all.

Audience Relevancy: Learning how to make balloon animals is cheap, entertaining, and can be shared with other people.

The purpose of this laboratory experiment is to construct a mousetrap vehicle. The vehicle needed to go travel five meters. My partner and I build a mousetrap car that obtain a two-axle vehicle with four CDs making the produce optimum acceleration and travel.

We were given groups to design and make a mousetrap powered car that will roll as far as possible. This will be measured and be put into a graph. We will make three modifications to our mousetrap car over the course of the experiment. We have a variety of different materials, including plastic, wooden wheels and a dowel, screws, mousetrap, blue tack and a piece of string. Forces were acting in a negative way and a positive way on the car. Gravity was pulling the car down to the ground. Uplift was pushing up upon the car against gravity. Drag was also known as friction, holding back the car while it was moving. Thrust was in the cars favour, pushing forward against the force drag. There were also many forms of energy being used and being wasted like heat and sound energy. Potential energy was stored in the mousetrap, propelling itself forward. Kinetic energy was also demonstrated when the car started to roll.

In our to be a Mechanical Engineer class we had to transfer a stuffed pikachu doll into the container (pokeball) down below. The pikachu doll had to be transferred on a trolley of our own design on a 52’ and 1” plastic coated 1/16” steel cable at a slant downward angle. If it is possible to close the lid do so. For the trolley the design specifications should be safe to use, easy to operate, it can’t be no longer than 32” and weigh more than 4 lbs, and lastly the device must be purely mechanical with no electronics, combustion, liquids, chemical reactions, or compressed

On the two maps U.S. Military Engagements Abroad 1789-1860,and U.S. Trade Partners 1783-1860, a lot of the trade routes line up in the same places.Why are trade and war occurring in the same places?What makes war occur what makes trade so popular around war?Military and trade partner maps is aligned way to often for them not to have something to do with each other.

With the average of the first car being only 2.76 metres and the remodelled car achieving 5.78 metres. This shows that the balloon improved the distance by a massive 3 metres. The remodelled car achieved a much further distance than the original car. 6. Propose future modifications and/or

One of the most fun projects this year, building mousetrap racers. With this project, however, challenges arose. Attaching the wheels to the axles, for example, presented a major problem. The dowel used was .75 inch and was too large to fit in the center of the DVD. Using washers and bolts was thought of, but they proved to be too heavy. In the end, bottle caps and screws worked to secure the wheels to the axles. The bottle caps were wide enough that when fitted against the DVD they wouldn't go through the hole. Another challenge was placing the mouse trap as far from the drive axle as possible without impeding the car’s movement. So an arm extension on the mousetrap was not constructed so upon snapping it would not hit the front axle.

CornelCookson is a leading manufacturer of overhead coiling doors and custom closure products. One of their most popular products is the steel slated rolling steel door (see Figure 1), which is used to provide security and weather protection across a wall opening of a building. An astragal (see Figure 2), which is a weather seal, is supplied at the bottom of the door to help prevent the transfer of fluids from one side of the wall to the other. The current material of the astragal is Thermoplastic Vulcanizate (TPV), which is composed of 40%

The balloon powered race car will be powered by the balloon. The balloon will be blown into and the straw will be the source of the air going into the balloon and then pinched so there is no release of air, then release the air, measure the distance and speed of the car when air is released. This uses the three Newton laws and they are when an object is at rest it stays at rest and an object is in motion it stays in motion in a straight line at constant speed unless acted upon by an unbalanced force, the next is the acceleration of an object depends on the mass of the object and the force applied, the last is every action there is an equal and opposite reaction.

The Radio Flyer All-Terrain is an amazing red folding wagon with wooden stake sides and air tires to handle any terrain. With all-steel construction, this great red wagon is designed to handle adventures both on and off road. It comes with some extra-long handle folders under for easy storage and its controlled turning radius can prevent tipping while turning round corners. Additionally, the rugged 10 inch air tires will provide you with a smooth ride on any terrain. Built for children aged one year and older, this product features a steel body that lends it a durable performance. Its no-pinch ball joints will keep your fingers safe, so it is extremely

For the rocket we build the nose of the rocket first. To make the nose we cut the top portion out of the second two liter bottle. Then we will need to cut out a slit on the bottle in the shape of a rectangle. We made sure to leave one side attached to the bottle. We cut the very top of the nose and replaced the top with a half of a ping-pong ball for the tip of the nose. Then after the nose was dried we secured the ping pong with duct tape. In the inside we took the balled up clay and glued it down to the inside of the nose for stability . Then we started to make the wings. We cut the 2 large taperd fins out of the foam board and 2 smaller tapered fins . We then attached the wings that were covered in red duct tape for decoration to the

For this project, I made a device that will safely stop an egg falling from various heights without the egg cracking. My device was a box, made of cardboard, with three ramps, also of cardboard, inside of it; each ramp was at a different angle so that the egg can roll down smoothly. The first ramp has a “bed” made of duct tape that crosses to the opposite side of the box. The “bed” has a hole in it so the egg can pass through. Each ramp is padded with paper towels, as are the walls above the second and last ramp. Each ramp is attached to the box with duct tape, but not enough to make the ramp completely stiff. Each slope should have some flexibility to increase the time of impact during the collision of the egg on the ramp. Every time the egg

The toy has uses two main energies, Kinetic and Potential. Potential energy is made by the pulling back of the car. Kinetic is made when after the car is
