1 2 Two rods of different materials having coefficients of thermal expansion a and a2 and Young s moduli Y and Y 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 and junction does not shift If a and a are in the ratio 2 3 the thermal stress developed in the two rods are equal provided Y Y is equal to 2 1 2 3 3 3 2 2 1 1 4 4 9
