Hi! So when this system gets heated, how does the wire expand if it is bent like that? Would it expand horizontally or vertically? Also, when calculating the stress for the wire, I know that I use the thermal expansion equation for dL of steel, but other people said that you have to also subtract that by dL of aluminum, why? I can't picture that in my head for some reason.
My process was:
Stress in wire = Y(αΔT)
and the answer I got was 2.4*10^7 N/m^2
