Homework 02 3-7. The man attempts to pull down the tree using the cable and small pulley arrangement shown. If the tension in AB is 60 lb, determine the tension in cable CAD and the angle which the cable makes at the pulley. 3-15. The unstretched length of spring AB is 3 m. If the block is held in the equilibrium position shown, determine the mass of the block at D. 8 D A 20 B 30 3 m -3 m- KAC-20 N/m wwwwww 4 m www KAD = 40 N/m KAB = 30 N/m 3-11. Determine the maximum weight W of the block that can be suspended in the position shown if cords AB and CAD can each support a maximum tension of 80 lb. Also, what is the angle for equilibrium? 3-57. If each cord can sustain a maximum tension of 50 N before it fails, determine the greatest weight of the flowerpot the cords can support.
