Question

A pendulum consisting of a string of length L attached to a bob of mass m swings in a vertical plane.

(a) When the string is at an angle θ to the vertical, calculate the tangential acceleration of the bob using ΣFt = mat. (Use any variable or symbol stated above along with the following as necessary: g and θ.) (solved)
at = gsin(θ)

(b) What is the torque exerted about the pivot point? (Use any variable or symbol stated above along with the following as necessary: g and θ.) (unsolved)
