## Homework Statement

For the rubber band model, calculate the fractional change in (L-L

_{0}) that results from an increase δT in temperature, at constant tension. Express the result in terms of the length and temperature.

## Homework Equations

U=cL

_{0}T

τ=bT((L-L

_{0})/(L

_{1}-L

_{0})); τ=tension, L

_{1}=elastic limit

d/dL(1/T)=d/dU(-τ/T)

## The Attempt at a Solution

I'm sort of at a loss on this one. I've tried subbing in all sorts of equations, but can't seem to make any real progress.
