A car having a mass of 5500 kg is pulled slowly up a steep inclined track by a steel cable (see figure). The cable has an effective cross-sectional area of 320 mm2, and the angle of the incline is 310. What is the tensile stress σt in the cable?
A steel tube has a mean diameter of 100mm and a thickness of 3 mm. Calculate the torque which can be transmitted by the tube with a factor of safety of 2.25 if the criterion of failure is maximum shear stress
