Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Could change or remain unaltered depending on which link is fixed Will remain same Will change Will not occur Could change or remain unaltered depending on which link is fixed Will remain same Will change Will not occur ANSWER DOWNLOAD EXAMIANS APP

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