Q. A 1510 kg car rests on four tires, each of which is inflated to a gauge pressure of 210 kPa. What is the area of contact of each tire with the road, if the four tires support the weight equally?
Q. A car traveling on a flat (unbanked) circular track accelerates uniformly from rest with a tangential acceleration of 1.90 m/s2. The car makes it one quarter of the way around the circle before it skids off the track. Determine the coefficient of static friction between the car and track from these data.
