Theory of Machine Angle of ascent of cam is defined as the angle Through which the cam rotates during the period in which the follower remains in highest position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower Through which the cam rotates during the period in which the follower remains in highest position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because The system is unbalanced Bearing centre line coincides with the axis The shafts are rotating at very high speeds Resonance is caused due to the heavy mass of the rotor The system is unbalanced Bearing centre line coincides with the axis The shafts are rotating at very high speeds Resonance is caused due to the heavy mass of the rotor ANSWER DOWNLOAD EXAMIANS APP
