Question

Hello I am having trouble solving this problem. Please show all work. I know this is a long one so thank you ahead of time.

Selecting a suitable lifting mechanism for placing gasoline pipes underground is a vital step in 15000 psi 까 AntB -Point B pipeline construction projects. Segment #66 of the below pipeline is being lifted simultaneously Stress by two cranes with hook blocks, and each hook block weighs 800 lb. Segment #66 is 80 ft. long with a unit weight of 538 lb./ft. The project manager selected cranes with cables made out of a material for which the stress vs. strain curve is shown here. 9,000 psi! / Point A 0.00031 0.000517 Strain The length of the cable is 15 ft and possible diameters for cross-sections listed below. Assume the total load is distributed evenly on four cables, as shown in the below picture. You can neglect the weight of the cable itself. Assume the yield strength of the cable material to be the material you determined (If there is same modulus of elasticity with same materials, choose highest yield strength on the table)
