Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Will change Could change or remain unaltered depending on which link is fixed Will remain same Will not occur Will change Could change or remain unaltered depending on which link is fixed Will remain same Will not occur 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) r ω₁.ω₂.r (ω₁ + ω₂) r (ω₁ - ω₂) 2r (ω₁ - ω₂) r ω₁.ω₂.r (ω₁ + ω₂) r (ω₁ - ω₂) 2r ANSWER DOWNLOAD EXAMIANS APP
