Theory of Machine A combination of kinematic pairs, joined in such a way that the relative motion between the links is completely constrained, is called a Mechanism Structure Kinematic chain Inversion Mechanism Structure Kinematic chain Inversion 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 distance between fixed pivots of crank and followers is 95 mm Slightly less than 95 mm Slightly more than 95 mm 45 mm 95 mm Slightly less than 95 mm Slightly more than 95 mm 45 mm ANSWER DOWNLOAD EXAMIANS APP
