Theory of Machine A system of masses rotating in different parallel planes is in dynamic balance if the Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero Resultant force is equal to zero Resultant force and resultant couple are both equal to zero Resultant couple is equal to zero Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero Resultant force is equal to zero Resultant force and resultant couple are both equal to zero Resultant couple is equal to zero ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine At the nodal point in a shaft, the amplitude for torsional vibration will be Minimum Maximum Infinity Zero Minimum Maximum Infinity Zero ANSWER DOWNLOAD EXAMIANS APP
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 proportional to the square of the speed Unbalanced forces are not dangerous at higher speeds Effects of unbalances are directly proportional to the speed Unbalanced couples are caused only at higher speeds Effects of unbalances are proportional to the square of the speed Unbalanced forces are not dangerous at higher speeds Effects of unbalances are directly proportional to the speed ANSWER DOWNLOAD EXAMIANS APP
