An equilateral triangle ABC is formed by joining three rods of equal length and D is the mid point of AB. The coefficient of linear expansion for AB is \alpha_1 and for AC and BC is \alpha_2 If distance DC remains constant for small changes in temperature, then the relation between \alpha_1 and \alpha_ 2 is

An equilateral triangle ABC is formed by joining three rods of equal length and D is the mid point of AB. The coefficient of linear expansion for AB is α1 and for AC and BC is α2 If distance DC remains constant for small changes in temperature, then the relation between α1 and α2 is

α1=4α2
4α1=α2
α1=2α2
2α1=3α2
