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 = 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 n = 3(l - 1) - 2j ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A torsional system with discs of moment of inertia I₁ and I₂ as shown in the below figure, is gear driven such that the ratio of speed of shaft B to shaft A is 'G'. Neglecting the inertia of gears, the equivalent inertia of disc on shaft B at the speed of shaft A is equal to I₂/G² I₂/G G².I₂ G.I₂ I₂/G² I₂/G G².I₂ G.I₂ ANSWER DOWNLOAD EXAMIANS APP
