It depends on the car and how compressed "crushed" is, but a ball park answer follows. Pressure is force divide by an area (F/L^2). A typical person can sit on a car and not crush it (~5 to 20 psi (pounds per square inch.)). To crush the car would require more pressure, so 100 to 500 psi would provide a range of crushed levels of a car.

Oct 26, 2016· If you're looking for the specifics to snap a piece of your skeleton, it takes about 4,000 newtons of force to break the typical human femur. But don't run out and start applying pressure to femurs and then get upset at us when things don't crack correctly. A lot depends on the bone itself, its position in the body, and the angle of attack.

The carbon atoms found in coal are squeezed and heated, and then pushed toward the earth's surface, where they cool and become diamonds. Plants are the source material for coal, and most diamonds are much older than the earth's first land plants. This means the earth's diamond deposits were created long before the existence of coal.
