Please explain how to derive
this and provide the answer.
A bar of length L and uniform density is held horizontally against a wall by a pivot at one end and a rope of tension T which pulls up and to the left making an angle θ with the vertical wall. The rope is attached to the bar at a distance l L from the wall. A mass M is resting at the end of the bar. If the bar...

A uniform rod of mass M = 5.02kg and length L = 1.08m can pivot
freely (i.e., we ignore friction) about a hinge attached to a wall,
as seen in the figure below.
The rod is held horizontally and then released. At the moment of
release, determine the angular acceleration of the rod. Use units
of rad/s^2.
