Physics · Elasticity and Thermal Stresses
Two rods of different materials having coefficients of linear expansion α1, α2 and Young's moduli E1, E2 respectively are fixed between two massive rigid walls. The rods are heated such that they undergo the same increase in temperature. There is no bending of the rods. If α1 : α2 = 2 : 3 and the developed thermal stresses are equal, what is the ratio of E1 to E2?
