A metallic rod, containing masses at its edges, is used to deflect the shaft.
The deflection can be measured through a protector and the extent to which the spring was deflected initially can also be found.

Specification:

• Axis mounted on ball bearings.
• 2 levers with sliding weights.
• Integrated angle measuring scale mounted on axis.
• Wall mounting plate made of anodised aluminium.
• Vibration Of Spiral Spring Apparatus
