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 G.I₂ I₂/G² I₂/G G².I₂ G.I₂ I₂/G² I₂/G G².I₂ ANSWER DOWNLOAD EXAMIANS APP
