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) 2r (ω₁ - ω₂) r ω₁.ω₂.r (ω₁ + ω₂) r (ω₁ - ω₂) 2r (ω₁ - ω₂) r ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In the below figure, PC is the connecting rod and OC is the crank making an angle θ with the line of stroke PO and rotates with uniform angular velocity at ω rad/s. The Klien's acceleration diagram for determining the acceleration of the piston P is shown by quadrilateral CQNO. The acceleration of the piston P with respect to the crank-pin C is given by ω² × CO ω² × NO ω² × CN ω² × QN ω² × CO ω² × NO ω² × CN ω² × QN ANSWER DOWNLOAD EXAMIANS APP
