Question

At a building site, a 1000 kg container hangs from a crane cable and is then placed on the floor so that the cable is unloaded. The container is pushed to an elevator shaft, where it is to be lowered by the crane. By mistake, there is a 1-m slack in the cable from the crane when the container is pushed into the elevator shaft. Calculate the maximum stress in the cable if the cable has a cross-sectional area of 500 mm2 , an effective elastic modulus of 70 GPa, and is 25-m long from the crane to the container.

Answer 1

Solution. 1000X9.87 m. 2. criven : mass container (m) = 1600 kg. Weight 9810 N. h = (ross-sectional area of cable = soomm = 500mm² = 500010-6 m2. length of cable(d) = 25 m. in = 70 upa Ym? we know that If 2hAE If 70x109 W mark A 14 lap = 9810 Soox106 2X1 XS 80x1082oxio 9810 x 25 351669.6 11.04 N Ans ma
