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)2r (ω₁ + ω₂)r ω₁.ω₂.r (ω₁ - ω₂)r (ω₁ - ω₂)2r (ω₁ + ω₂)r ω₁.ω₂.r ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A friction circle is a circle drawn when a journal rotates in a bearing. Its radius depends upon the coefficient of friction and the Radius of journal Magnitude of the forces on journal Clearance between journal and bearing Angular velocity of journal Radius of journal Magnitude of the forces on journal Clearance between journal and bearing Angular velocity of journal ANSWER DOWNLOAD EXAMIANS APP
