Experiment No 1
Balancing of Rotating Masses
Aim :To balance the rotating masses experimentally by determining the required mass to
balance the unbalance force caused by rotating masses.
Apparatus: Balancing Machine, Weights with bolts, nuts and washers,
Aim: To determine the Pressure distribution in Journal bearing
Apparatus Required: Journal bearing set-up, Tachometer, weigths
Lubricants are used to control friction, rubbing, wear and tear of parts while
operating in a high speed
Whirling of shaft
Aim: To determine the critical speed of the given shaft theoretically & verify
the same through experiment.
Apparatus: Non contact type Tachometer, whirling shaft setup, scale
