Theory of Machine Angle of action of cam is defined as the angle Through which the cam rotates during the period in which the follower remains in the highest position Moved by the cam from beginning of ascent to the termination of descent Moved by the cam from the instant the follower begins to rise, till it reaches its highest 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 the highest position Moved by the cam from beginning of ascent to the termination of descent Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Of rotation of the cam for a definite displacement of the follower ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) ω₁.ω₂.r (ω₁ - ω₂)2r (ω₁ - ω₂)r (ω₁ + ω₂)r ω₁.ω₂.r (ω₁ - ω₂)2r (ω₁ - ω₂)r (ω₁ + ω₂)r ANSWER DOWNLOAD EXAMIANS APP
