Quarter Car Essay

Anti-Lock Brake System (ABS) is a combination of vehicle hardware and software that work together to maintain steering control and vehicle stability during hard braking. Initially developed as a special option for topof-the-line models, today’s ABS units are compact, easy to service, inexpensive and widely available. Now every major automotive manufacturer offers some form of ABS vehicle control that provides safe, maximum braking under all weather conditions and road surfaces.

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.

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

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. (See APPENDIX 1 for detailed

The final car uses a combination of a mousetrap and rubber bands. The mousetrap, attached to the top of the car by tape, pulls a fishing line which is wrapped around the front axle. The fishing line is attached to the mousetrap at an arm that was added to the mousetrap. The arm is comprised of two long axles attached to the hammer of the mousetrap which allows the fishing line to pull the car's axle for a farther distance. The long chassis of the car allows for the arm to be as long as it is. If the arm was much longer than the body of the car, the spring force of the mousetrap and the weight distribution of the arm would cause the car to flip. However, by distributing the weight of the arm across the body of the car, the car was able to maintain

Cars with built in safety features like anti-lock brakes, side air bags and automatic safety belts cost less to insure. Cars that are frequently stolen generally have higher insurance premiums. You can check with the Highway Loss Data Institute for theft reports on the make of car you are considering buying.

a) When the lever is winded up and all set for release the Mousetrap Car (MTP) has potential energy that will be used to accelerate the car. 2) When the lever is released the string is pulled from its ready position on the axle causing the level to pull the string causing a pulling force on the string by the lever. 3) When the lever is released and the string is pulled the back wheels of the MTC are beginning to move because of the potential energy that is now kinetic energy which causes rolling friction between the Mousetrap Cars wheels and the ground. 4) The MTC is now accelerating at a certain speed from it's point with the string being pulled by the lever until the spring is snapped, which then causes the MTC to

We usually avoid buying a stolen car, a vehicle with outstanding finance, a car with insurance write-off, and the one that has been marked as scrapped. We usually need to know about previous owners as well as the valuation of the vehicle before buying it. A Car Check can verify all these things along with many other important factors. A car check is also needed by law to ensure that the car on the road are safe for the environment as well as for people. A vehicle check is usually performed before purchasing a car to end the scepticism regarding crucial concerns; For instance, whether the car had previous plates or not, is the car stolen, insurance write-off, whether it is a good investment for the buyer, and

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

Bad greetings a car salesman will always use are, "Can I help you?" or "Can I get someone for you?" or the ever-popular, "Can I help you or get someone for you?". Now a good greeting they tend to use are "Welcome to Pizza Mazda of Reading. I 'm Ed and you are...?". To prove this concept, I did my own digging and discovered some interesting things about car salespeople. Whether we do or don’t trust them they are trying to make a living as they best see fit. However, what we cannot ignore are the tricks these good-looking people use on us.

National Association for Stock Car Racing (NASCAR) begin the process of branding its sport over sixty years ago; therefore, becoming the most widely watched auto racing sport in the United States. From its inception in 1948, owner and founder, William Henry France, quickly realized this sport could potentially be a profitable endeavor. In 1959, France opened the first paved track – The Daytona International Speedway, which of course is located in – Daytona Beach, Florida. There were more tracks to ensue after the Daytona International Speedway opened its gates. Because the popularity of NASCAR had risen to a profitable popularity status, many companies began partnering with the business; therefore, paved the way for the automobile industry to start the process

A locked-up wheel provides low road handling force and minimal steering force. Therefore, the main benefit of ABS operation is to maintain directional control of the vehicle during emergency braking.
