The 5-lb lamp, with center of gravity located at G, is supported by the parallelogram linkage of negligible weight. Find the tension in the spring AD when the lamp is in equilibrium in the position shown. (Hint: the vertical distance between B and E is the same as the vertical distance between A and C.) 2. The blade of the bulldozer is rigidly attached to a linkage consisting of the arm AB which is controlled by the hydraulic cylinder BC. There is an identical linkage on the other side of the bulldozer. Determine the magnitudes of
