This Inertia Bar is an essential apparatus for demonstrating the principles of rotational dynamics and moment of inertia in physics laboratories. It is specially designed to help students observe how a rigid bar behaves under torsional oscillations when suspended through its central axis.

 The apparatus consists of a solid brass rod measuring approximately 30 cm in length and 1.5 cm in diameter. A central pin-vice is provided for securely holding the suspension wire during the experiment. The sturdy brass construction ensures proper balance, durability, and reliable performance in repeated laboratory use.

 Supplied complete with a wall bracket for convenient suspension, the Inertia Bar is suitable for mechanics experiments in schools, colleges, universities, and educational physics laboratories.
