This set up has been designed to perform and verify the principles involved in study of vibrations. It consists of a basic frame and various components and sub assemblies designed for quick changeover and easy assembly of number of experiments in vibrations. A speed controller unit is provided for forced vibration experiments.

With this unit following experiments can be conducted –

Pendulum Experiments

For Pendulum a sub frame is attached to upper beam. Two Chucks and Hardened V guide is provided for carrying experiments.

Experiment - 1 - Simple Pendulum

To verify the relation

and plot graph T² Vs. L

Experiment - 2 - Compound Pendulum

1. To verify the relation K² + (OG)² T = 2 p g (OG)
2. To determine the radius of gyration and equivalent length of compound pendulum.
