Two rods of different materials having coefficient of thermal expansion `alpha_(1) and alpha_(2)` and Young's modulues `Y_(1) and Y_(2)` respectively are fixed betwee two rigid massive walls. The rods are heated such that these undergo same increase in temperature. there is no bending of the rods. if `alpha_(1):alpha_(2)=2:3`, the thermal stress developed in the two rods are equal, provided `Y_(1):Y_(2)` is

Two rods of different materials having coefficient of thermal expansion alpha_(1), alpha_(2) and young's modulii Y_(1) ,Y_(2) respectively are fixed between two rigid massive walls. The rods are heated such that they undergo the same increase in temperature. There is no bending of rods. If alpha_(1) :alpha_(2)=2 : 3 , the thermal stresses developed in the two rods are equal provided Y_(1) : Y_(2) is equal to
