Question

5. A four-bar kinematic chain is represented by a quadrilateral ABCD in which AD is fixed and is 400 mm long. The crank AB, 75 mm long, rotates in a clockwise direction at 120 rev/min and drives the link CD, 125 mm long, by means of the connecting link BC, 350 mm long. Determine the angle through which CD oscillates and find the angular velocities of the links BC and CD in one of the positions when BC is perpendicular to AB. (U. Lond.) (Answer: 93°; 1.1075 rad/s; 8.13 rad/s)
