Two rods of L1 and coefficient of expansion @1 are conected freely to a third rod of L3 and and coefficient @2 to make an isosceles triangle. arrngement is supported by a knife edge on the midpoint of L3. for the apex of the triangle to remain at a constant distance from the knife edge :
ans:L1/L3=1/2*(@1/@2)^1/2
