i) The initial length of the bar is 50 inches. Determine the length of the bar when the force of 5000 lbs is applied. ii) This aluminum alloy is used for a cable to support an elevator cab that weighs 10,000 lb. Calculate the minimum diameter of the cable required to support the cab without permanent deformation. iii) The aluminum alloy has a final gage length after failure of 2.195 inch and a final diameter of 0.398 inch at the fracture surface. Calculate the ductility of this alloy.
