Homework Statement
For the rubber band model, calculate the fractional change in (L-L0) that results from an increase δT in temperature, at constant tension. Express the result in terms of the length and temperature.
Homework Equations
U=cL0T
τ=bT((L-L0)/(L1-L0)); τ=tension, L1=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.
