Question:

A force of {eq}25\ lb {/eq}. is required to compress a spring of natural length {eq}0.80\ ft {/eq} to a length of {eq}0.75\ ft {/eq}. Find the work done in compressing the spring from its natural length to a length of {eq}0.70\ ft {/eq}.

Work Done On A Spring

The work done to compress the spring, which depends on the spring constant {eq}k {/eq} as well as the distance of deformation {eq}x {/eq}, is described by the equation below:

$$\displaystyle W= \int(kx)\,dx\\ $$
