A uniform slender rod of length `L` and mass `M` is pivoted at one end. It is held horizontal and releasaed. Assume the pivot is frictionless. Find .
(a) the angular acceleration of the rod immediately after it is released, and
(b) the force `F_(0)` exerted on the rod by the pivot immediately after release.
