This unit is designed to study the characteristics free vibration of a bending bar. When a bar is loaded with some weight and given a deflection, it starts oscillating. The time period and frequency of oscillation depends on the mass and dimensions of the bar.
The unit consists of a rectangular frame on which the bar can be placed in any direction. The bar is fixed at one end and mass is added on bar at other end. The unit contains a proximity sensor as well which measures the time period and frequency of the vibrating bar. The waveform of the vibration can be seen by oscilloscope.
