Extracted text: (b) During a manufacturing operation a tray of product is oscillated under a water spray by the action of a connecting link AB and crank OB as shown in Fig. 3(b). For the instant when 0 = 15°, the angular velocity of AB is 0.086 rad/s anti-clockwise. Answer each of the following: (i) Draw the velocity diagram for v, =v, +v (ii) Find the linear velocity, va, of the tray. (iii) Find the angular velocity of the crank OB. 900 mm 300 mm Fig. 3(b)
