1. A metal wire 25 ft long, hanging vertically, supports a load of 750 lbs. Neglecting the weight of the wire, determine the required diameter if the stress is not to exceed 15 ksi and the total elongation is not to exceed 0.35 in. Assume E = 29 x 105 psi. 2. A steel tire, 12 mm thick, 80 mm wide, and 1.5 m inside diameter, is heated and shrunk onto a steel wheel 1500.5 mm in diameter. If the coefficient of static friction is 0.35, what torque is required to twist the tire relative to the wheel? Neglect the deformation of the wheel. Use E = 200 GPa.
