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 clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ - ω₂)r (ω₁ + ω₂)r (ω₁ - ω₂)2r ω₁.ω₂.r (ω₁ - ω₂)r (ω₁ + ω₂)r (ω₁ - ω₂)2r ω₁.ω₂.r 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/G I₂/G² G.I₂ G².I₂ I₂/G I₂/G² G.I₂ G².I₂ ANSWER DOWNLOAD EXAMIANS APP
