Question

A rappelling rope used for outdoor programs, rescue and industrial work, can safely support a weight "W" (in pounds) provided, where "d" is the rope's diameter (in inches). Determine the diameter of rope that would be needed to support a weight of at least 5,500 pounds.

Answer 1

D = ( d * 5500 ) / W

Explanation:

Diameter of rope " d " supports "w" weight

i.e. d = W

d ( inches ) = W ( pounds )

? ( inches ) = 5500 pounds

The Unknown diameter D ( ? ) = d * 5500 / W
