Air pressure and normal force exerted by surface of road

Reference no: EM13655346

An automobile weighing 1.05 X10⁴ N has weight equally distributed overits wheels. The weight of the car causes each tire to be slightlyflattened on the bottom so that there is a surface area in contactwith the road. The gauge pressure of the air in the tire is1.97X10⁵ Pa(28.565 lb/in²). Find the area of contact, assuming that the only forces on the section of tire incontact with the road are the air pressure and the normal force exerted by the surface of the road.
