Theory of Machine A simple spring-mass vibrating system has a natural frequency of fn. If the spring stiffness is halved and the mass is doubled, then the natural frequency will become 8 fn 4 fn fn/2 2 fn 8 fn 4 fn fn/2 2 fn 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 G².I₂ I₂/G G.I₂ I₂/G² G².I₂ I₂/G G.I₂ ANSWER DOWNLOAD EXAMIANS APP
