Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced forces are not dangerous at higher speeds ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a disc clutch, if there are n₁ number of discs on the driving shaft and n₂ number of discs on the driven shaft, then the number of pairs of contact surfaces will be n₁ + n₂ + 1 n₁ + n₂ n₁ + n₂ - 1 n₁ + n₂ - 2 n₁ + n₂ + 1 n₁ + n₂ n₁ + n₂ - 1 n₁ + n₂ - 2 ANSWER DOWNLOAD EXAMIANS APP
