Mousetrap Car Friction

I designed the top view and side view of the car. In addition, I considered the friction arrows. After deciding the size of my dragster, I did a streamline design. After these processes, I traced it on the balsa wood for the scroll saw to cut later, and I dug two holes for the wheels. I exactly adhere to my design; moreover, I used sandpaper to make the dragster smooth. When all these steps were completed, the dragster was painted with black and a little bit of green, then I put a "brand". Finally, I put on the straws and mounted the wheels and washers on the dragster.

We worked well, but the car stopped halfway while I was testing the car with 150g weights on the track because the weights were blocking the wheels. I solved this issue by adjusting the weights and the car never stopped while I was testing on the track. (The major problem we faced this week). We decided to put 100g weights on the car because our energy was high when I tested the car on the

The problems that we had with the friction was that it kept on stopping our vehicle. The concrete floor had some bits and pieces in the way and was a little bumpy in the area we tested (not the real test). We solved this friction problem by clearing the concrete floor and finding an area that is not bumping, which doesn’t interfere with our mousetrap racer going.

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.

In this case we need to overcome the friction force from the axles, and tires to be able to power the vehicle by mousetraps far enough. There is a coefficient of friction between the axle and the bearing where the axle sits in the bearings and does not spin together so that is where most of the friction is created. The front wheels currently are hard rubber, and the rear wheels are currently cutting disks which are a hard material and very skinny, creating a very little amount of friction. The total force of friction would need to be less than the force of the mousetraps on the axle throughout the traps angular travel. Methods that were used to reduce friction consists of using lubrication on the axles to make it easier to spin, use skinnier wheels to reduce friction from the ground, and making the vehicle lighter with a simpler design.

The background research had talked about different types and sizes of wheel and the distance in can cover in a certain amount of time.

Purpose: The purpose of this experiment is to determine the coefficient of kinetic friction using kinematics and to determine the coefficient of static friction using two methods. The first is when it slides down the ramp and the second is when it is at equilibrium. Hypothesis:

From 13,000 fans during the first race 50 years ago to over 300,000 fans at a single event today, the NASCAR sport has evolved over the years in various ways. In the beginning, stock car drivers actually bought brand-new cars from dealers and went racing. The first strictly stock car race sanctioned by NASCAR in Charlotte, North Carolina in 1949 had no safety requirements for competing cars. They were true stock cars in every sense of the word, completely unmodified and in hindsight, incredibly unsafe. There were no extra or special requirements for drivers and cars that raced than there were for street vehicles. Today, NASCAR race cars have very little in common with street cars because almost every detail of a NASCAR vehicle is handmade.

1.My assignment was to construct a mousetrap car. It should take from 4-5 days to finish, I finished it in 4 days.You could only able to use 3 pieces of wood, 4 CD, 4 pieces of rubber, 4 washers,4 axles,1 long stick of iron,1 string and1 mouse trap.

In conclusion, my 1st car was a bust traveling 9.8 cm/s, my 2nd car did pretty well traveling 35.86 cm/s, but wasn’t built very well and lastly my 3rd car was the most successful, traveling 50.16 cm/s. Over the time that I worked on this project my skills really did advance. In the beginning, I was clueless and now, with the materials, I could make another car in a day. I learned a lot from trial and error.

My mousetrap car, of course, was going to run into multiple problems from friction to loose wheels, from short work times too long hours researching, but I am proud of the final product created. Some of the problems I ran into were the two types of frictions that affected my car and caused me to go back to the drawing board, the two frictions being rolling friction and sliding friction. Rolling friction was caused by the wheels of the car having bad traction and my wheels being too heavy, while sliding friction was caused by the axle on the front and back rubbing against the body of the car. Friction would also cause my car to slow down, and there were plenty of times when the string used for my car to start was worn down pretty fast by the
