Report On The Car Engines

The Cummins diesel engine was manufactured in the year 1919 by its creator Clessie Cummins. The Cummins was put in a variety of vehicles and the most common are in the dodge ram 2500, 3500, 4500, and 5500 series rams. It is also put into more heavy-duty trucks such as Peterbilt semis. The reason people choose Cummins over Chevy’s Duramax or Ford’s Powerstroke is because Cummins’ are built to last longer meaning they can go more hours without maintenance. The Cummins diesel engines have several different designs, and a number of different models, and assembling one takes money, time, effort, and knowledge.

455 horsepower and 455 lb-ft of torque make it the most powerful iteration of the Chevrolet Camaro SS so far.

Stopping, just as important as acceleration the ability to slow or stop quickly and safely are important traits of performance, this can be indicated by braking distance from a certain speed, where a shorter stopping distance is more desirable measure of performance. The Corvettes performance shows that it fits the great sports car mold. Speed, power and the ability to hug the road, are all part of the experience of driving a truly great sports car. The Corvette delivers in all these areas, it has a 0-60 MPH time of less than 5 seconds, and a time of slightly less than 14 seconds in the quarter mile. In the 525 foot slalom test an average speed of 47.9 mph was obtained. On the skid pad the Corvette is able to obtain 0.96 lateral g’s (Stewart, 2007). The Corvette’s stopping power is noted in its ability to come to a complete stop from 60 miles per hour in only 125 feet (Mueller, 1998). These performance measures may not be used in everyday driving, but the ability to stop quickly in an emergency situation is apparent, as is having enough acceleration to merge onto a busy highway, with the performance the Corvette has, these everyday tasks can be accomplished effortlessly and safely.

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.

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.

When the mousetrap car moves down the track, the speed of the mousetrap car decreases, therefore my hypothesis was supported. At 1 second, the mousetrap car was traveling at a speed of 3.2 m/s. At 2 seconds, the mousetrap car was traveling at a speed of 2.35 m/s. At 3 seconds, the mousetrap car was traveling at a speed of 1.53 m/s. At 4 seconds, the mousetrap car was moving at a speed of 1.2 m/s. At 5 seconds, the mousetrap car was traveling at a speed of .98m/s. “A car will eventually come to a stop if just allowed to roll as the friction between the road surface and the wheels causes friction that causes the vehicle to stop,”(Examples of Rolling Friction). The evidence supports the claim because the wheels of the mousetrap car are moving

The Physics of NASCAR by Diandra Leslie-Pelecky: How can a car going 190 mph operate with precision? How can race car drivers walk away from disastrous crashes? The author, a physicist, caught a NASCAR race on television and wondered those same things. In The Physics of NASCAR, Leslie-Pelecky explores the science

The car, being above the ground, has gravitational potential energy. Which, when placed on the ramp, transforms into kinetic energy. This kinetic energy pushes the car down the ramp, towards the ground and the momentum carries the car forward. The wheels allow it to gain more distance, as using wheels is the most effective way of transporting something. Having only 3 groups of wheels reduces friction compared to having 4 groups of wheels.

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

Final Conclusion Entry The purpose of my mousetrap car design was to explore how far my car would travel with the laws of motion, friction, potential energy, and kinetic energy acting upon the car. I designed the car to be light and long, with the car being 45 centimeters in length, having a lever arm of 24 centimeters, and a mass of 82.3 grams, because the car would use more string to rotate the axle when the car is longer and less force would be needed to propel the car with less mass. I used 4 wheels congruent to each other with a diameter of 7.5 centimeters. I used rubber bands fasteners to align the car.

According to “slighshot” it is very clear that speed is a major requirement in racing that was presented by car. It is also observed that different racers having different speed limits and driving expertise and this makes car racing to be an interesting sport, for both the participants of the races and the spectators who really enjoyed to be part of the race. Individual with innate desires of car racing started purchasing many cars and from the video they are seen assembling in various places to take place in the car racing activities. Mechanics also had a

For this speed analysis, I used Limpert’s analysis of a rotating vehicle. I utilized the sine value of the angle determined by the path of travel of Vehicle 1 versus the angle of approach at measured distances during the rotation. In conjunction with the standard speed loss equation, the sine value is applied to the coefficient of friction value. The result based on this analysis is a speed loss range of 22.85 mph to 29.50 miles per hour during

     Acceleration and Speed are obviously the two defining characteristics of a fast car. Newton’s three laws of motion are an essential part in determining how fast a
