In a zoo, a Metal-A cable with initial length of 4 meters and initial diameter 1 cm is needed to lift up an injured elephant with mass in 1350 kg. For safety purpose, safety factor of 4 is used and the Metal-A diameter elongated to be 4.013 meters when carry the elephant. The Metal-A wire is remains elastic deformation after putting down the elephant. 2). i) Calculate the engineering stress that exerted on the Metal-A cable. ii) Determine the percentage of elongation, and engineering strain on x, y and z-axis directions of the cable due to the tensile load. iii) Determine the final diameter, and percentage of reduction of area of the Metal-A cable under the applied tensile force.
