The pressure in the tyres of a vehicle is 280 kPa. The contact area of each of the four tyres on the ground is 0.012m^2. Calculate the weight of the vehicle.
Force = Pressure x Area
The Attempt at a Solution
280 kPa = 2800000 Pa
Force = 2800000 x 0.012 = 33,600N
Am I right in assuming that this is the weight of one tyre, so you have to multiply this by 4 to get the force of the whole vehicle on the ground??
I think I've gone completely wrong here so would be grateful for some help!
