Math Problem Statement
A torque of 44 N·m producing a counter clockwise rotation is applied to a wheel about its axle. A frictional torque of 16 N · m acts at the axle. What is the net torque about the axle of the wheel
Solution
The net torque () acting on the wheel can be found by considering the applied torque and the opposing frictional torque.
Given:
- Applied torque () = 44 N·m (counterclockwise)
- Frictional torque () = 16 N·m (clockwise)
Since counterclockwise torque is considered positive and clockwise torque negative, the net torque will be:
So, the net torque is in the counterclockwise direction.
