Problem 2 on Coriolis Component of acceleration / Velocity and acceleration diagram

The driving crank AB of the quick return mechanism, as shown in diagram revolves at uniform speed of 200 rpm. Find the velocity and acceleration of the tool box R, in the position shown, when the crank makes an angle 60° with the vertical line of centres PA. What is the acceleration of sliding block at B along the slotted lever PQ.? Please support my channel, subscribe and share my videos with friends.
