SUMMARY
Torque does no work in situations where it is balanced, meaning the net torque acting on an object is zero. This occurs when the angle between the force applied and the lever arm is 90 degrees, resulting in no rotational movement. Additionally, torque does not perform work when an object is in static equilibrium, where all forces and torques are balanced, preventing any motion. Understanding these principles is essential for analyzing mechanical systems.
