Theory of Machine Cam angle is defined as the angle 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 the 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 the highest position ANSWER DOWNLOAD EXAMIANS APP
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 minimum length of the coupler will be 45 mm Slightly less than 45 mm Slightly more than 45 mm 95 mm 45 mm Slightly less than 45 mm Slightly more than 45 mm 95 mm ANSWER DOWNLOAD EXAMIANS APP
