Vibration Of Spiral Spring Unit .

Vibration Of Spiral Spring Unit

The unit consists of a flat spiral spring attached between ball bearings mounted shaft and a fixed bracket. The spiral spring is formed by a cold rolled steel strip. Two-arm lever is fitted to the shaft diametrically opposite each other. Two sliding weights on the lever can be securely

attached in position using clamping screws. These sliding weights can change the moment of inertia of the spiral spring-rotating mass system. 

This system is displaced by hand. The spring deflection is measured with a scale disc that is also attached to the shaft, and the oscillation frequency (or period of oscillation) is measured by a stopwatch
