3. A four-bar inverted crank-slider mechanism is shown below. Node A is the R joint between the input link and the coupler. B is a point on the coupler (link 3). Using a proper velocity scale and draw a velocity diagram. Determine (i) the angular velocity of link 4 and the relative velocity of link 3 to link 4, (ii) the linear velocity of point B by means of the velocity image theorem or the relative velocity diagram, (iii) the Coriolis acceleration a43/44, and (iv) the relative slidign acceleration a3/44 [20] Ao 1 2 A Scale: 1:10 @2 150 rad/s (ccw) 4 3 1 Ba B
