The wheel of a car has a radius of 0.350 m. The engine of the car applies a torque of 272 N·m to this wheel, which does not slip against the road surface. Since thewheel does not slip, the road must be applying a force of static friction to the wheel that produces a countertorque. Moreover, the car has a constant velocity, sothis countertorque balances the applied torque. What is the magnitude of the static friction force?
