Homework Statement
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
Homework Equations
x(t)=A cos((omega)(t)+(phi))
ma=??
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!
