Homework Statement
Two identical masses with a mass of m each are connected by a rigid bar of negligible mass and rotate in a vertical plane in an anti-clockwise direction.
Homework Equations
If the system is released from rest when it is in a horizontal position, determine the angular acceleration of motion.
The Attempt at a Solution
So far, this is my progression towards a final solution. Firstly, find the moment of inertia of the system:
I=Ʃ(r^2)(m)
= (d-a)^2(m) + (a)^2(m)
= (d-a)(d-a)(m) + (a)^2(m)
= md^2 - 2adm + 2ma^2
I'm getting stuck after I do this, because I have no idea what to do after I find the moment of inertia in order to find the angular acceleration. I have attached an image to help the visualisation of the situation. Your help would be greatly appreciated! :)
