Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to Two lower pairs and one additional link Any one of these Two lower pairs and two additional links One lower pair and two additional links Two lower pairs and one additional link Any one of these Two lower pairs and two additional links One lower pair and two additional links 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 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)r (ω₁ - ω₂)2r (ω₁ - ω₂)r ω₁.ω₂.r (ω₁ + ω₂)r (ω₁ - ω₂)2r ANSWER DOWNLOAD EXAMIANS APP
