when the angular velocity of a balanced rotating body increase it can lose its balance true...
Homework Answers
False.The balanced body is designed for the constant angular velocity of the shaft . only when angular velocity of the shaft increases propornatly the angular velocity of the balanced body increases in static balancing. If without relation or reference if angular velocity of balancing body is varied then there may be imbalance in the system.

when the angular velocity of a balanced rotating body increase it
can lose its balance true...
