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 G².I₂ G.I₂ I₂/G I₂/G² G².I₂ G.I₂ I₂/G I₂/G² ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a Hartnell governor, the stiffness of the spring is given by (where S1 and S2 = Spring forces exerted on the sleeve at max. and min. radii of rotation, and h = Compression of the spring) (S₁ + S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / h (S₁ - S₂) / 2h (S₁ + S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / h (S₁ - S₂) / 2h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the anticlockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ - ω₂) 2r (ω₁ - ω₂) r (ω₁ + ω₂) r ω₁.ω₂.r (ω₁ - ω₂) 2r (ω₁ - ω₂) r (ω₁ + ω₂) r ω₁.ω₂.r ANSWER DOWNLOAD EXAMIANS APP
