The car, as seen from the front, is traveling at a constant speed υc on a turn of constant radius R that is banked at an angle θ with respect to the horizontal. The coefficient of static friction between the tires and the road is μs. The car’s center of mass is at G.

Figure P7.76

Determine the bank angle θ so that there is no tendency to slip or tip, i.e., so that no friction is required to keep the car on the road.
