If I let air out of my tires to increase surface area on sand; wont that just reduce the pressure on the sand too? Is traction NOT a function of both pressure and surface area? Physics
In: Physics
Gravity is the force being applied here. Reducing air pressure in the tire just means that gravity will flatten the tire (decreasing the volume inside) until the pressure force rises enough to counteract gravity. This results in the same force on the ground, but a flatter contact surface.
