Question

A car weighs 15,000 N and its tires are inflated to a pressure of 190,000 Pa. How large is the area of the car's tires that are in contact with the road? Please show work.

Answer 1

Assuming 4 tires, weight supported by each tire is 3750 N. This is provided by the pressure in the tires.

Thus the area in contact at each tire is 3750/190000 m² = 19736 mm²
