Q1 The four-bar mechanism with the crank AB 40 mm long, rotates in clockwise direction at a speed of 300 rpm. At the instant when the crank makes 90° with the frame AD is shown in Figure Q1. The lengths of other links are given in the diagram. Using graphical method perform the following: (1) Draw the space diagram. [20] (ii) Draw the velocity diagram neatly and estimate the relative velocity of point C with respect to the frame. [40] (iii) Draw the acceleration diagram and determine angular acceleration of the link BC. [40] 80 C B 40 70 A D 50 ALL DIMENSIONS ARE IN mm Figure Q1 90⁰
