Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will Become equal to R/2 Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 Become equal to R/4 Become equal to 2R Remain same as before 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 G.I₂ G².I₂ I₂/G I₂/G² G.I₂ G².I₂ I₂/G ANSWER DOWNLOAD EXAMIANS APP
