A uniform rod of mass m and length 2L is bent into 2 straight segments about its

midpoint. The angle between the 2 segments is α. The bent rod is balanced on a sharp

fulcrum. Find the angular frequency for small oscillations if the rod is displaced from

equilibrium and released.

know total mass of rod: m

length: 2L

angle between rods is: alpha

2. Relevant equations

x(t)=A cos((omega)(t)+(phi))

ma=??

3. The attempt at a solution

I've tried to draw a diagram explaining the motion, and forces involved and I can tell that the "tension" or force that the rod applies at the center of mass of each length of the rod is responsible for the restoring force, however I am not sure how to treat this in order to write newton's second law so that I can solve the 2nd order differential equation for the angular frequency. Help is greatly appreciated!
