Q.

Two rods of different materials having coefficients of linear α1 and α2 expansion and Young’s modulii Y1 and Y2 respectively are fixed between two rigid massive walls. The rods are heated such that they undergo the same increase in temp. There is no bending of rods. If α1 : α2 = 2:3 . The thermal stresses developed in the two rods are equal if Y1 : Y2 is equal to
