I have learned quite a lot while constructing my mousetrap car. For example i learned that the friction that is active while the mousetrap car is in motion is rolling and static. Rolling friction occurs when an object rolls over a surface, in my case the CDs are rolling on the floor causing the car to move. Static friction occurs when one solid surface slides over another, for example my solid car sliding over a solid surface.Fortunately i didn't have very much problems related to friction. For my design I decided to go with a 3” by 10” plastic base with 4 CDs wrapped in rubber balloons for the extra friction. When deciding on a number of wheels for my car i just choose four because i personally think with four wheels you get the equal amount …show more content…
I cut the arm down to about 9” so it can be a little shorter than the base. I didn't cut it to short or to long because it needs to be able to reach the back axle for the string to wind up. My first time making the car the wheels were uneven and wobble which caused the car to curve when in motion causing it to knock into everything in sight. Fortunately i was able to fix that problem with the help of my hot glue gun. I glued each side of my CDs to the axle to help with the stability of the wheels and the car. Another big thing about the car is that it can't be to heavy or it wont move at all or just move slowly and not go the distance you would …show more content…
All together i built, broke, and rebuilt my car 3 times. At first the base was made out a black foam poster board and broke the first time i let it go off. After that I replaced the weak poster board with a stronger plastic base and stabbed thin wooden rods it for support. The problem with the second one was the wobbly wheels. I tried multiple things such as trying duct tape and superglue but then settled with the best idea which was hot glue, it dries fast and stays on longer than the others. And last but not least the third time i had trouble winding up the weak ribbon and traded it in for a stronger, more stable string. At last my car was finally finished and ready to get
My project consisted of a simple set of materials: a 30cm by 20cm cardboard box, a toilet paper roll, industrial glue, 2 rubber bands, 4 water bottles, 2 Oreo cookie trays, packaging tape, and lead shielding sheets. The lead sheet was flattened, form-fitted and glued on the inner bottom of the cardboard box. This was done in order to provide the box a low center of gravity and to meet the minimum mass of 1 kg. Glued to the lead sheet was
A mousetrap-powered car is a vehicle that powers up and moves by the energy of a wound-up mousetrap’s spring. Its main components are the mousetrap, long metal rod, and the fishing line. In order to make the car work, the rod was wounded-up (wrapped) around the fishing line that had one end attached to the drive axle and the other end to the arm of the mousetrap, which pulls the snapper's lever arm closer to the drive axle. When the arms were released, the tension of the spring pulled the string off the axle. As a result, the fishing line string unraveled, causing the axle and the wheels to rotate, propelling the vehicle. There are various forms of energy that are involved with this car. First, it started off as potential (stored) energy that came from when the mousetrap was set by wounding the spring around the axle by the turning of the wheels, which caused the snapper’s lever arm to pull closer to the drive axle and the spring in the center was compressed. Since every action has an equal and opposite reaction, when the trap was released, most of the potential energy converted into kinetic (motion) energy, propelling the snapper arm forward. However, not all of the energy was converted into kinetic energy, as some of it was lost to the force of friction. Friction helped to spin the wheels and progress the car forward as when the string was pulled, friction between it and the axle caused the axle to rotate. In addition, the outside forces of friction caused the car to slow down and eventually come to a stop. Since energy cannot be destroyed, when the car came to a stop, the friction converted into thermal and heat energy.
Rolling a Car down a Ramp Investigation PLANNING When planning my experiment, I will need to take into consideration. the following points: -Fair testing -Equipment -How many results will I get? -What range of variables I will experiment with I will be investigating, by varying the height of the summit of the ramp. is raised off the ground, if the average speed increases or decreases.
The story Jumping Mouse is a Native American tale that is told with many central themes in mind. The story was most likely told to a wide ranged age group. So with the multiple themes it most likely was design to touch home with all ages in some form or another. One of the more central themes however was the importance of the situations and animals that help Jumping Mouse on his journey. The animals that he meets are much the same as people and situations we have met or well meet in our lifetime.
The chassis is often regarded as the skeleton of the car. This skeleton is just not any skeleton. It should be able to handle a lotta stress when the car is experiencing enormous cornering G forces. These forces are brutal and the car would just fall apart if its not properly engineered. And moreover, just giving a heavy metal chassis is not going to suffice. The car should also be light. Heavy metals would by no doubt, make the car rigid as a bus. But a bus isnt something that we would call, sporty in any way. The cars which are taking part in serious competitions would have the weight criteria to be hardwired as much as possible.
“How about we use a pulley system with a weight at the end to push the car forward?” my team member suggested. “Or we could use a hammer launcher,” I proposed. We went back and forth, contemplating different methods. We faced trials, tribulations, and troubles in the design process. Building and perfecting our designs took weeks, but our coach guided us throughout the process and encouraged us to “Never give up!” We researched the effects of different factors that could potentially come in the way of our success and analyzed all of the device possibilities. Even when research got arduous and we couldn’t agree on something, we never gave up on our dream of placing in the regional competition. This was one of the hardest challenges I’ve ever faced in my Science Olympiad career, but our unfaltering dedication and our belief in success helped us persist in the face of setbacks. Once we finished our plan, we began to build the device. It was exhilarating to see our plan come to
Engine-manufacturing plants did not exist, so Ford's car was constructed entirely by hand, with common parts recycled into new uses. A house doorbell was the horn. The two cylinders were made from scrap pipe rescued from an old steam engine, honed and then cut in half (Taub 17-18).

The main advantage of the track over the wheels is that it can distribute a very large force over a large area. That means that instead of applying all the force on little area where wheels touch the ground, it applies it over the whole area of the track.
The battle between FWD and RWD last for 50 years. I’m writing this essay to prove that the RWD is the correct layout for 2WD vehicles. Customers are confused by the matter of which wheels actually drive the vehicle, and which is best for their particular needs. There are four main drive forms: front-wheel drive (FWD), rear-wheel drive (RWD), four-wheel drive (4WD) or all-wheel drive (AWD). Each has its advantages, and no single layout is best for all situations. Normally, sedan are based on the FWD and the RWD, the other two are used for SUV and trucks.
The force and impact of collisions have truly been based off the material that cars have been built with. In the past, cars were built with heavy parts and steel as it was believed to be a safe way to protect occupants in the car as the structure would be more solid. Although, this is not the case since with a heavier and stronger body, the time of the collision would be very minimal which would overall increase the force of the impact based on the car’s specific velocity and mass. On the other hand, modern cars utilise a specific feature called a Crumple Zone. The Crumple Zone is implemented in cars through the way they have been shaped with the metal. The metal in the outside of cars have been heated, cooled, and molded in a way to be able

I would recommend using an aluminium alloy to cast a cylinder block. It is ideal for the properties needed including having to withstand the heat and pressure that exists inside the engine block. The only difference that it has between the traditional engine block made of cast iron is that it has a low density which is ideal as it means it is lighter and therefore the car can travel faster. The blocks can be recycled back into aluminium parts again once finished with or can b...
