Theory of Machine The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints) n = 3(l - 1) - 2j n = (l -1) - j n = 2(l - 1) - 2j n = 4(l - 1) - 3j n = 3(l - 1) - 2j n = (l -1) - j n = 2(l - 1) - 2j n = 4(l - 1) - 3j 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 45 mm Slightly more than 95 mm Slightly less than 95 mm 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm 95 mm ANSWER DOWNLOAD EXAMIANS APP
