vibrations of different torsion bars

Description:

• In torsional vibrations, a restoring moment is produced by the twisting of a bar in the oscillating system.
• The restoring moment strives to return the rotating mass to the resting position.
• The TM 163unit can be used to study torsional vibration on torsion bars with different diameters and different lengths.
• At the top end, the torsion bars are clamped in a quick-action chuck.
• A solid circular disk or a circular ring is fixed at the bottom end of the bar using a quick-action chuck.
• They have the same mass and the same diameter, but different moments of inertia due to their shape.
• The torsion bars can be quickly and easily exchanged and their length varied.
• The oscillation period is measured.
• The experimental unit is designed to be fixed to a wall
