Problem
A cordless drill delivers a constant torque of 4.0 N·m while rotating at 1.20 × 10³ rev/min. The mechanical efficiency of the drill is 75 %, meaning only that fraction of the input work is transferred to the screw.
Determine the useful work, in joules, delivered to the screw during a 5.0 s interval of steady operation.
