8. A ½ inch diameter steel cable measuring 75 feet has a 1,000 lb load at its end, which rests on the ground. If initially the cable has no stress in it (the ground is supporting the full 1,000 lbs), determine the temerature decrease needed to make the load rise a total of 0.25 inch off the ground. E = 30 x 106 psi. Coefficient of Thermal Expansion for steel as = 6.5 x 106 in/in/deg F
