Question
Derive an expression for the power delivered by torque.
✓
Answer
Power delivered is the work done per unit time. IF we differentiate the expression for work done with respect to time, we get the instantaneous power $(P)$.
$ p =\frac{d w}{d t}=\tau \frac{d \theta}{d t} $
$ p =\tau d \omega $
