The lifting capacity of a cable is proportional to the areas of its cross section. If a cable is 1.5 inches in diameter will lift 10,000 pounds. What will a cable 0.625 inches in diameter lift?
-------------
Area is a function of the square of the radius.
The ratio is (0.625/1.5)^2 = (5/12)^2
Lifting capacity = 10000*(5/12)^2 = 1736 pounds
