Two rods of length L_1 and L_2 are made up of different material whose coefficient of linear expansion are alpha_1 and alpha_2 respectively. The difference between their lengths will be independent of temperature if L_1/L_2 is equal to.

Two uniform metal rods of length L_(1)andL_(2) and their linear coefficients of expansion alpha_(1)andalpha_(2) respectively, are connected to form a single rod of length (L_(1)+L_(2)) . When the temperature of the combined rod is raised by '' t^(@)C '', the length of each rod increased by the same amount then [(alpha_(2))/(alpha_(1)+alpha_(2))] is
