Bifilar Pendulum

A bifilar pendulum is a mechanical system used to study rotational motion and moment of inertia. It consists of a rigid body (a bar or disc) suspended by two parallel strings or wires, allowing it to oscillate in a horizontal plane. The plate is suspended by means of two strings of equal lengths from a rigid suspended (i.e. a heavy T-shaped clamp with two split chuck is provided on the heavy base).  It consists of a heavy cast iron rectangular plate of dimension 15x10x1.5cm.  When the plate is suspended freely, the two strings will be equally inclined to the horizontal face of the plate. The plate has six holes two holes on top, two holes on the front side and two holes on the third side of the top.
