Left: An operating pumpjacklinkage mechanism.DGEAΦBBTHWOARight: A mechanicalFigure 1 shows a pumpjack operating at an oil well. Its representation as a linkage isalso shown in Figure 1. The pumpjack is driven by a motor attached to crank OA. A constant torqueT' is applied to the crank and the crank rotates at a constant angular velocity wOA. A force P is appliedvertically downwards at the end of the walking beam BD, which has its centre of mass at point G.To design the mechanism, a careful kinematic analysis of the mechanism needs to beconducted. To avoid mechanical failure and to provide adequate support to the mechanism, theengineer needs to analyse the reaction forces in the joints. Masses of links OA and AB are assumedto be smaller in comparison with the mass of BD and are ignored in the analysis. Magnitude of forceP is equal to 10 kN and it is directed vertically upwards.At the instant shown, perform the following tasks using the individual values of lengths OA, AB, BC,OE, CE, L, H, angle ß, angular velocity wOA, mass mBD, and moment of inertia JBD. Length of thewalking beam BD is equal to 2-BC. Distance CG from point C to the centre of mass of the walkingBCbeam is equal to
