Theory of Machine A spring controlled governor is said to be unstable when the controlling force Increases as the radius of rotation increases Decreases as the radius of rotation increases Increases as the radius of rotation decreases Remains constant for all radii of rotation Increases as the radius of rotation increases Decreases as the radius of rotation increases Increases as the radius of rotation decreases Remains constant for all radii of rotation 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 I₂/G G².I₂ I₂/G² G.I₂ I₂/G G².I₂ ANSWER DOWNLOAD EXAMIANS APP
