2. (20 points) Figure 2 shows a four-bar linkage. Body 1 is the fixed link or the ground, body 2 is the crankshaft OA, body 3 is the coupler AB, and body 4 is the rocker BC. Using the complex-algebra approach, obtain an expression for the angular velocities of the coupler and the rocker in terms of the angular orientation and angular velocity of the crankshaft. Assume that the angular velocity of the crankshaft is constant and is equal to...

The dimensions of the planar mechanism, shown in Fig. 1 are
given in Table 1. Link 1 is rotating at
constant 120 rpm in counterclockwise direction. The external
force of 200N is applied on the slider
at point D against its translational motion. Assume the link
