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 Slightly more than 45 mm Slightly less than 45 mm 95 mm 45 mm Slightly more than 45 mm Slightly less than 45 mm 95 mm 45 mm ANSWER DOWNLOAD EXAMIANS APP
