Left: An operating pumpjack linkage mechanism. D G E A Φ B B T H WOA Right: A mechanical Figure 1 shows a pumpjack operating at an oil well. Its representation as a linkage is also shown in Figure 1. The pumpjack is driven by a motor attached to crank OA. A constant torque T' is applied to the crank and the crank rotates at a constant angular velocity wOA. A force P is applied vertically 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 be conducted. To avoid mechanical failure and to provide adequate support to the mechanism, the engineer needs to analyse the reaction forces in the joints. Masses of links OA and AB are assumed to be smaller in comparison with the mass of BD and are ignored in the…arrow_forward
- Exercise [2] As shown in Figure below, the velocity of water, v (m/sec), discharged from a cylindrical tank through a long pipe can be computed as: (/2gH V2gH tanh 2L V = L. Where g=9.81 (m/sec?), H=initial head (m), L= pipe length (m), and t = elapsed time (sec). Determine the head needed to achieve v= 5 m/sec in 2.5 seconds for a 4-m-long pipe by Newton-Raphson method.
