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

Two metal rods are fixed end to end between two rigid supports as shown in figure. Each rod is of length l and area of cross-section is A . When the systeam is heated up,datermine the condition when the juncation between rods does not shift ? ( Y_(1) and Y_(2) are Young's modulus of materials of rods, alpha_(1) and alpha_(2) are coefficients of linear expansion)

Two metal rods are fixed end to end between two rigid supports, as shown in figure. Each rod is of length 'l' and area of cross-section is A. When the system is heated up, determine the conditioin whenthe juction between rods does not shift. [Given, Y_(1) and Y_(2) are Young's modulus of materials of the rods, alpha_(1) and alpha_(2) are coefficient at linear expansion.
