5. Two uniform metal rods one of aluminium length 1, and another made of steel of length 12 and linear coefficients of expansion a, and as respectively are connected to form a single rod of length 1; +12. When the temperature of the combined rod is raised by t°C, the length of each rod increases by the same amount. Then GO

Two uniform metal rods one of aluminium of length l_(1) and another made of steel of length l_(2) and linear coefficients of expansion alpha_(a) and alpha_(s) 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 increases by the same amount then (l_(l))/(l_(1) + l_(2)) is

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

Two rods, one of aluminum and the other made of steel, having initial length l_1 and l_2 are connected together to form a single rod of length l_1 + l_2 . The coefficients of linear expansion for aluminum and steel are alpha_a, and alpha_s, respectively. If the length of each rod increases by the same amount when their temperature are raised by t^@C , then find the ratio l_1/(l_1 + l_2)
