This unit is designed to study the balancing of rotating objects. When an object rotates at any given velocity, it faces centrifugal force. This force unbalances the assembly which contains this object. The unit consists of a shaft which is supported by bearings on its both ends. Four masses are present on this shaft which can slide on the shaft and attain different angles as well. A pulley is present on one side of the shaft which connects the shaft with motor so that shaft can be rotated. Two buckets, detachable pulley and metallic balls are also included in this apparatus to find out the unbalance in static position due to rotating masses. The motor is provided with power via a function generator. The main element of the bench top unit is a smooth shaft to which four variable unbalance weights can be attached at any angle or distance. The rotor is supported horizontally in ball bearings and is driven by a speed-controlled motor. The speed is measured electronically and shown on a digital display. For determination of the unbalance weight by measuring the balance of moments the driving belt can be removed. Using different weights dragging on the pulley defined moments can be exerted to the shaft. They can be compared with those caused by the unbalance weights when rotating. The transparent hood prevents contact with the rotating parts and provides a good view of the rotor. Fastening of the supporting base with elastic elements neutralizes undesirable vibrations
