Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Will change Will not occur Could change or remain unaltered depending on which link is fixed Will remain same Will change Will not occur Could change or remain unaltered depending on which link is fixed Will remain same ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because The system is unbalanced The shafts are rotating at very high speeds Bearing centre line coincides with the axis Resonance is caused due to the heavy mass of the rotor The system is unbalanced The shafts are rotating at very high speeds Bearing centre line coincides with the axis Resonance is caused due to the heavy mass of the rotor ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A system of masses rotating in different parallel planes is in dynamic balance if the Resultant force and resultant couple are both equal to zero Resultant couple is equal to zero Resultant force is equal to zero Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero Resultant force and resultant couple are both equal to zero Resultant couple is equal to zero Resultant force is equal to zero Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero ANSWER DOWNLOAD EXAMIANS APP
