This apparatus is designed to demonstrate the concept of whirling in shafts and visualize its effects in heavy rotating machinery. When shaft rotates, transverse vibration produces in it. If the shaft is out of balance the centrifugal forces produces and vibration starts.
If the rotation of the shaft is equal to the natural oscillation of the shaft, then these vibrations are multiplied. In heavy machinery this phenomena is very dangerous and it must be controlled. This apparatus consists of number of shafts of different lengths and diameters, center support for shaft and end support. Shaft is coupled with motor and speed of motor can be varied to inspect the vibrations at various speeds.
