the 2-ft cord AB and spring AC. If the spring has an unstretched length of 2 ft, determine the angle 0 for equilibrium. Take k = 15 lb/ft. 3-23. Determine the unstretched length of spring AC if a force P 80 lb causes the angle 0 60° for equilibrium. Cord AB is 2 ft long. Take k 50 lb/ft. 2 ft 2 ft В Probs. 3–22/23 *3-24. The springs on the rope assembly are originally f unstretched when 0 = 0°. Determine the tension in each rope when F and D. 90 lb. Neglect the size of the pulleys at B 3-25.
