1. For the mechanism shown in Figure 1, consider the position where the various coordinates are those given below the figure. The point C denotes the center of curvature of the slotted link at the position denoted by D. When the mechanism is in the position shown, the crank BD has an angular velocity and angular acceleration given by, W = 17.440k rad/sec, a2 = 12.410k rad/sec. Determine the angular acceleration of link 3 at this position. C+ 3 Figure 1: Slider mechanism. A = [0.000, 0.000] B = [1.250, 1.670] (ft) C = [1.710, 0.010] (ft) D = [1.950, 1.130] (ft)
