Find the ratio of the lengths of an iron rod and a n aluminium rod for which the difference in lenghts is independent of temperature .Cofficients of linear expansion of iron and aluminium are 12 X 10 -6 / 0 C and 23 X10 -6 / o C respectively. HOW T O APPROACH THIS PROBLEM AND WHAT'S THE ROLE OF "DIFFERENCE IN LENGHTS IS INDEPENDENTOF TEMPERATURE IN SOLVIN THE PROBLEM"
