Difference between static balancing and dynamic balancing:
Static Balancing:
Static balancing is considered and applied only when the system of masses revolves in one plane.
When the centre of the system acts on the axis of rotation then the system is under static balancing.
This type of balancing system is used for small and medium objects or parts like gears, fans, etc.
Dynamic Balancing:
Dynamic Balancing is considered or applied when the system of masses revolves in different planes.
When there is no force and the resultant couple is acting on the system then the system is under dynamic balancing.
This type of balancing system is used for heavy equipment and the different size of parts like turbines, motors, etc.
