In the four-bar linkage system shown, the lengths of the bars AB and CD are LAB = 46 mm and LCD = 25 mm, respectively. In addition, the distance between points A and D is dAD = 43 mm. The dimensions of the mechanism are such that when the angle θ = 132°, the angle ϕ = 69°. For θ = 132° and , determine the angular velocity of bars BC and CD as well as the velocity of the point E, the midpoint of bar BC. Note that the figure is drawn to scale and that bars BC and CD are not collinear.
