Interactive solution 9.1 presents a model for solving this problem. the wheel of a car has a radius of 0.380 m. the engine of the car applies a torque of 456 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 countertorque. moreover, the car has a constant velocity, so this countertorque balances the applied torque. what is the magnitude of the static frictional force?
