Give the expression for the torque acting on a simple pendulum about the support.

Text Solution

Verified by Experts

Torque on a simple pendulum about the support is due to the tangential component of the force.
Torque `=-L(sm sin theta),` where .L. is the length of the pendulum. The negative sign indicates that the above the torque tends to reduce the angular displacement.
