Homework Statement
As in picture b) a uniform rod is displaced by a small angle a, the question is to find its frequency.
(small angle approximations are allowed)
Homework Equations
Mtotal*a c.o.m=Fext
The Attempt at a Solution
I figure the only relevant external force is the komponent of gravity tangential to the center of masses path. This force is equal to mgsin(a) a beeing the angle of displacement from the vertical(of the center of mass). This seems to produce the standard differential equation that I would have for a point particle. Where is my mistake? My solution is not correct
