Two metal rods of the same length and area of cross-section are fixed end to end between rigid supports. The materials of the rods have Young module `Y_(1)` and `Y_(2)` , and coefficient of linear expansion `alpha_(1)` and `alpha_(2)` . The junction between the rod does not shift and the rods are cooled

Two rods AB and BC of equal cross-sectional area are joined together and clamped between two fixed supports as shown in the figure. For the rod AB and road BC lengths are l_(1) and l_(2) coefficient of linear expansion are alpha_(1) and alpha_(2) , young's modulus are Y_(1) and Y_(2) , densities are rho_(1) and rho_(2) respectively. Now the temperature of the compound rod is increased by theta . Assume of that there is no significant change in the lengths of rod due to heating. then the time taken by transverse wave pulse to travel from end A to other end C of the compound rod is directly proportional to
