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 G.I₂ G².I₂ I₂/G I₂/G² G.I₂ G².I₂ I₂/G ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The advantage of the piston valve over the slide valve is that in the former case The pressure developed being high provides tight sealing Power absorbed is less Wear is less Both wear and power absorbed are low The pressure developed being high provides tight sealing Power absorbed is less Wear is less Both wear and power absorbed are low ANSWER DOWNLOAD EXAMIANS APP
