Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is 45 mm 95 mm Slightly more than 95 mm Slightly less than 95 mm 45 mm 95 mm Slightly more than 95 mm Slightly less than 95 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine Angle of action of cam is defined as the angle 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 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 ANSWER DOWNLOAD EXAMIANS APP
