Question 1. Assume you are working in an agricultural machinery company and tasked to design and develop a produce processing unit. As shown in Fig. 1, a part of the design

requirements is that the roller trays of the produce are to be oscillated under water sprays by the action of the connecting link AB and the crank OB. For the instant when 8 = 25 degrees, the angular velocity of the link AB is 1.5 rpm clockwise, Determine (a) the angular velocity of the crank OB (b) the velocity of the tray at A, and (c) explain the change in direction and magnitude of the tray and the crank if the angular velocity of the link AB has been doubled.
