Figure 8 (c) Figure 9 illustrates a four-bar linkage mechanism that is used to operate a washing system on a vegetable harvesting line. The mechanism consists of a crank OA which moves in a limited arc and an L-shaped connecting rod AB which tilts a large bucket of water DB onto the vegetables. The crank rotates with a constant angular velocity wOA = 4x rad/s. For the instant shown with the crank vertical and the angle 8 = 30° determine...
