a simple pendulum is displaced to the left of its equilibrium position and is released from rest. set the origin of the coordinate system at the equilibrium position of the pendulum, and let counterclockwise be the positive angular direction. assume air resistance is so small that it can be ignored.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
