1. The problem statement, all variables and given/known data 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!
