Figure 1. A uniform rod suspended from pivot point P.
A uniform rigid rod of mass \( M \) and length \( L \) is suspended from a horizontal pivot point \( P \) that is located a distance \( x \) from the center of mass of the rod, where \( 0 < x < L/2 \). The rod is free to swing in a vertical plane without friction. The acceleration due to gravity is \( g \).
