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 = 4(l - 1) - 3j n = 2(l - 1) - 2j n = 3(l - 1) - 2j n = (l -1) - j n = 4(l - 1) - 3j n = 2(l - 1) - 2j n = 3(l - 1) - 2j n = (l -1) - j ANSWER DOWNLOAD EXAMIANS APP
