The wheel of a car has a radius of 0.300 m. The engine ofthe car applies a torque of 240 N*m to this wheel, which does not slip against the road surface. Since the wheel does not slip, the road must be applying a force of static friction to the wheel that produces a counter torque. Moreever, the car has a constatnt velocity, so this counter torque balances the applied tourque. What is the magnitude of the static frictional force?
