Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Effects of unbalances are directly proportional to the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The equivalent length of a simple pendulum which gives the same frequency as a compound pendulum is h²/(kG² + h²) h/(kG² + h²) (kG² + h²)/h (kG² + h²)/h² h²/(kG² + h²) h/(kG² + h²) (kG² + h²)/h (kG² + h²)/h² ANSWER DOWNLOAD EXAMIANS APP
