Two rods of different materials having coefficients 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 the 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

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

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 with coefficients linear thermal expansion alpha_(1), alpha_(2) , and Young's moduli Y_(1) and Y_(2) , respectively are fixed between two rigid walls. They are heated to have the same increase in temperature . If the rods do not bend and if alpha_(1) : alpha_(2) = 2 : 3 , then thermal stresses developed in the two rods will be equal when Y_(1) : Y_(2) ie equal to
