Static And Dynamic Balance

Static Balance:-
Static balance occurs when the centre of gravity of an object is on the axis of rotation. This allows the object to remain stationary, with the axis horizontal, without the application of any braking force. Static balance has no tendency to rotate due to the force of gravity.

Dynamic Balancing:-
Dynamic balancing is when the rotation does not produce any resultant centrifugal force or couple. The system will rotate without needing the application of any external force or couple, other than that required to support its weight. When a system or machine is unbalanced, to avoid stress being put upon the bearings, a counterbalancing weight is added. Dynamic balancing is a way to balance out machines by rotating parts quickly and then measuring the imbalance using electronic equipment. The imbalance calculated can then be added or subtracted from the weight until the vibration of the parts is reduced.

Static balance refers to the ability of a stationary on object to its balance. This happens when the objects centre of gravity is on the axis of rotation. Whereas dynamic balance is the ability of an object to balance whilst in motion or when switching between positions.

For any form of balance to happen, the centre of gravity must be aligned over the objects support base. The centre of gravity refers to the part which is the centre of an object weight. Balancing plays a very important part in machines. Balancing in machines helps to rotating bodies to avoid vibrations; vibration in machines can lead to failure. Common failure occurs in generators and heavy machinery, so undertaking in balancing can help to avoid machines from breaking down.

Balancing can also involves shifting the centre of gravity towards the centre of rotation. Dynamic balancing is when the rotating system doesn’t yield any other force or couple. Other than the force that is needed the system will rotate without the need for any additional external force or pressure to be applied.

Static balancing definition refers to the ability of a stationary object to its balance. The occurs when a parts centre of gravity is on the axis of rotation. However, the dynamic balance definition is the ability of an object to balance whilst in motion or when switching between positions.

Undertaking in balancing whether it be static or dynamic can help to extend the service life, quality and accuracy of your machinery. Unbalanced parts can lead to your machine breaking down or worst of all catastrophic failure.
