The four bar mechanism shown in Figure 2 has links of lengths OA = 100 mm, AB= 260 mm, BC = 180 mm, and the distances OD = 60 mm, OC = 180 mm and AD = 80 mm. If link OA rotates counter clockwise at a constant rate of 10 rads/sec, determine the angular velocities of the links AB and BC. Hint: [8 marks] use VA VB+WAB X TA/B. D' B Figure 2: This Figure relates to Question 2 (b) Determine the acceleration of the point A on the four bar mechanism shown in Figure 2. (c) Determine the angular accelerations of the links AB and BC. [3 marks] [9 marks]
