4) [10 marks] A steel cable is being used to hoist a load of mass Mload 3.3 metric tons through a vertical height L. The steel cable has mass density p 7600kgm3 and tensile strength S-2.5 x 108 Pa. For safety reasons, the stress in the cable (that is the force per unit area) must not exceed Smax - 0.8S. In this question, the mass of the cable cannot be neglected . First assume that the cable has uniform cross-sectional...

A 25mm diameter steel rod 1.5m long is being used in a rigid structure. For this steel the Ultimate Tensile Stress is 410 MPa Young’s Modulus is 200 GPa The rod is to be subjected to a tension load of 40 kN. Design requirements are that the rod cannot extend by more than 0.5 mm and that there is a Factor of Safety of 5 for the tensile stress. Determine whether or not the rod is adequate for the task:...

1. A tank 8m in diameter is to carry an internal pressure of 120 KPa. Determine the minimum thickness of the tank plating if the stress is limited to 40 MPa. 2. A rod with cross-sectional area at 100mm^2 is stretched between two fixed points such that the initial tensile load is 10 kN. The rod has a modulus of elasticity equal to 180 GPa and a coefficient of linear expansion or 0.0001m/m*degree C. The initial tension is designed such...
