Balancing of

Rotating Masses

29.1. INTRODUCTION

We have already discussed in the last chapter

about the centrifugal force. We know that whenever

a body is rotating or attached to a rotating shaft, it is

subjected to centrifugal force. This force tends to bend

the shaft and produce vibrations in it.

These dynamic forces not only increase the

loads on bearings and stresses in the various members,

but also produce unpleasant and even dangerous

vibrations.

It is therefore, very essential that all rotating

bodies should be completely balanced as far as

possible.
