Theory of Machine The inversion of a mechanism is Turning its upside down Obtained by fixing different links in a kinematic chain Changing of a higher pair to a lower pair Obtained by reversing the input and output motion Turning its upside down Obtained by fixing different links in a kinematic chain Changing of a higher pair to a lower pair Obtained by reversing the input and output motion 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 Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds ANSWER DOWNLOAD EXAMIANS APP
