Static Balancing A system of rotating masses is said to be in static balance if the combined mass centre of the system lies on the axis of rotation, static vs dynamic balancing. Condition for static balancing : The net dynamic force acting on the shaft is equal to zero. In other words, the centre of

A machine has many moving parts. Some machines have balancing of rotating masses motion and some of them have reciprocating motion. If these moving parts are not in complete balance, inertia forces are set up which may cause excessive noise, vibration, wear and tear of the system. Thus, balancing is the process of designing or
