How do you measure the wieght of a car using only 4 pieces of paper and a pressure guage?

Answer 1

I think this is how it's done:

You know that pressure is equal to force over area (P = F/A). You know that gravity is exerting a force on the car (mg) that is distributed about the car's tires. You can drive the car on the paper to make tire marks on the paper, and then use these marks to measure the area of the tire that touches the ground at any given time. Then, use the pressure guage to find the tire pressures of each of the tires. Multiply the total pressure and the measured areas of the tires. The answer you have should be the weight of the car in newtons. If you want, you can find out how to convert from newtons to pounds.

Answer 2

You cannot. The system of forces includes the forces inside the tire material as well. The deformation of the tires due to the weight of the car is also influenced by the properties of the tire. A softer tire will deform more than a harder tire with the same pressure. What if you had nearly solid hollow tires? The pressure inside would be no indicator of the forces outside. In reality, tires are too rigid for the experiment to work.

Answer 3

you can't. A pressure gauge only tells you how much air is in the tire or other container. It doesn't anything else. you would need more technical equipment. you would need to measure the thicknes of the tires first, lower the auto on it(1 on all 4 tires) and than remove the papers remeasuring the thickness of them, an dknow how much weight it would take to make the difference. multiupl that by 4 to arrive at the answer.
But with 4 peices of paper and a pressure gage which only measures pressure in the tire or other container you can get the cars weight. The gape only tells yo how much air is in the tire, and tries varry from auto to auto.

Answer 4

Put a sheet under each tire and draw the outline of the tire "footprint". Then find the area of each footprint in square inches. If you use the tire guage to find the tire pressure in pounds per square inch, just multiply the tire pressure by the area of the combined footprints to get the weight of the car.
