Problem 9 on relative velocity method / Whitworth quick return motion mechanism

Diagram shows the structure of Whitworth quick return mechanism used in reciprocating machine tools. The various dimensions of the tool are as follows OQ= 100 mm, OP=200 mm, RQ =150 mm, RS =500 mm The crank OP makes an angle of 60°with the vertical. Determine the velocity of the slider S ( cutting tool) when the crank rotates at 120 rpm clockwise. Find also the angular velocity of link RS and velocity of sliding block T on the slotted lever QT.
