Linear Expansion - Finding temperature

[QUOTE="JoeyBob, post: 6465321, member: 684467"] [B]Homework Statement:[/B] See attached [B]Relevant Equations:[/B] change length= a*original length * change in temp So if I am understanding the question correctly, I need to find the change in temperature that causes one rights outer radii to be the same as another rings inner radii. Now what I tried is two equations change length_1= a_1*original length_inner * change in temp change length_2= a_2*original length_outer * change in temp But the problem is that there is one too many unknowns here - i don't know the temp, change in L_1 or change in L-2. Either there's another equation I am missing or I am using the wrong approach. [/QUOTE]
