Consider a string that rotates around the end of a motor. The string has length L = 0.20m and mass M = 0.015 kg. What (constant) torque must the motor exert on the string for it to bring it from rest to full speed in 0.50 s? Full speed is 1200rpm. Igore wind resistance. The moment of inertia for motion of a rod about the end is I=1/3ML^2.

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
