Briefly describe with the aid of diagrams the relative motive motion analysis methods for a rigid body in general plane motion. In the mechanism shown in the Figure Q2(b), when = 20 and B = 15, the piston rod of hydraulic cylinder is extending at a speed of 20 cm.s which is decreasing at the rate of 8 cm.s. Given d = 26 cm, determine (i) the angular velocity and angular acceleration of link OA and (ii) the velocity and acceleration of the collar B relative to link OA Evaluate the effect of acceleration of piston on the motion of link BC and justify the answer using the dynamic fundamental.
