Aha, another one of these rotational problems. I thought I had escaped them. Gravity does indeed supply the restoring force and I fell into the same old physics student trap. Approaching this with Newton's second law for rotations, we get the sum of all the external torques= (Moment of...

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...
