1. Rope AB and AC are both made from DupontTM Kevlar 29 brand fibers. The cross-sectional areas and lengths of wires AB and AC are 0.4 in² and 20 ft, and 0.5 in² and 13 ft, respectively. If the weight attached to both ropes is 2000 tons, and if the allowable deformation in the ropes is 1 mm, will the system fail? 30° W 50°
