Theory of Machine A point B on a rigid link AB moves with respect to A with angular velocity ω rad/s. The radial component of the acceleration of B with respect to A, is (where vBA = Linear velocity of B with respect to A) v²BA /AB vBA × AB vBA /AB v²BA v²BA /AB vBA × AB vBA /AB v²BA ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A combination of kinematic pairs, joined in such a way that the relative motion between the links is completely constrained, is called a Structure Mechanism Kinematic chain Inversion Structure Mechanism Kinematic chain Inversion ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because Resonance is caused due to the heavy mass of the rotor The shafts are rotating at very high speeds The system is unbalanced Bearing centre line coincides with the axis Resonance is caused due to the heavy mass of the rotor The shafts are rotating at very high speeds The system is unbalanced Bearing centre line coincides with the axis ANSWER DOWNLOAD EXAMIANS APP
