Theory of Machine The relation between number of pairs (p) forming a kinematic chain and the number of links (l) is l = 2p - 3 l = 2p - 5 l = 2p - 2 l = 2p - 4 l = 2p - 3 l = 2p - 5 l = 2p - 2 l = 2p - 4 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 45 mm Slightly more than 95 mm 95 mm Slightly less than 95 mm 45 mm Slightly more than 95 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs) n = 2(l - 1) - 2j - h n = 2(l - 1) - 3j - h n = 3(l - 1) - 2j - h n = 3(l - 1) - 3j - h n = 2(l - 1) - 2j - h n = 2(l - 1) - 3j - h n = 3(l - 1) - 2j - h n = 3(l - 1) - 3j - h ANSWER DOWNLOAD EXAMIANS APP
