Key Features
- Cradle mounts on the test frame and suspends both pendulums
- Metal rod pendulum with a heavy sphere supplies the percussion force
- Wooden (compound) pendulum absorbs the impact, like a bat held underhand
- Hardened steel knife edges on a smooth cradle surface let the wooden pendulum pivot freely
- Visible horizontal movement at the pivot shows any reaction

About This Product
Students first find the centre of gravity of the wooden pendulum and use it to calculate its radius of gyration and centre of percussion. They then swing the metal sphere into the wooden pendulum at points above, below and at the centre of percussion and note the reaction each time. The set-up mirrors a ball striking a bat.
Frequently Asked Questions
