Question

The four tires of an automobile are inflated to a gauge pressure of 2.3 105 Pa. Each tire has an area of 0.027 m2 in contact with the ground. Determine the weight of the automobile.

Answer 1

I think the pressure is actually 2.3E5 Pa. That would make more sense.

Answer 2

Force = Pressure x Area

Force = (2.3105 Pa) x (0.027 m2)

Force = 0.062384 N

Note: That would be the force per tire. Multiply by 4

Force x 4 = 0.249536 N

Something tells me you've either got a model car, or one of your original data is incorrect (probably the pressure, which might look considerably better in kPa instead of Pa).
