The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the

A Unbalanced couples are caused only at higher speeds
B Unbalanced forces are not dangerous at higher speeds
C Effects of unbalances are proportional to the square of the speed
D Effects of unbalances are directly proportional to the speed

Correct Answer: Effects of unbalances are proportional to the square of the speed
