Resonance System

A flexible metallic strip fitted on a plastic moulded base (90x90x43) mm approx. and loaded at the top with a detachable brass weight, which vibrates in various modes on applying a sigl generator to the electromagnetic coil via. 4mm colour coded sockets. The amplitude of vibration can be directly monitored on a CRO with the help of Piezo electric transducer, bonded on the metallic strip and output comes out on 4mm colour coded sockets marked as output to CRO. A thin alluminium vane produces mechanical damping when it is moving in a small vessel containing water and the amount of damping is controlled by the depth of water used for studying the effect of damping on resonce.
