HVT3 Compound Pendulum

HVT3 Compound Pendulum

A wall mounted bracket has a metre long bar suspended from its knife-edge pivot point. Attached to the pendulum bar is a movable mass. The mass can be fixed along the pendulum bar in seven positions.

A simple cord pendulum with adjustable pendulum mass is also included. This enables the radius of gyration of the compound pendulum and the acceleration due to gravity to be determined.

Other investigations from this experiment include centre of gravity of a compound pendulum; effect of fulcrum position and comparison with a simple pendulum.

To time the pendulum motion a stopwatch is provided whilst accurate positioning of the pendulum mass is achieved using the ruler provided.
