The distance a spring stretches is directly proportional to the force applied to the spring. A 4lb weight stretches a spring 20 in. A 16lb weight stretches a spring 26 in. Find the length of the spring with no weight attached.

The length a spring stretches is directly proportional to the force applied. If a force of x pounds stretches a spring h inches, how much force is necessary to stretch the same spring m inches? (Assume x = 7, h = 4, and m = 15.)

With no weight the spring will be 18 in. Every 1Lb stretches the spring 1/2 In. The spring moves 6 inches (from 20 to 26 inches) with an incremental 12 Lbs (4Lb to 16LB)
