Questions
Two rods of different materials having coefficients of linear expansion and Young's moduli , 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 , the thermal stresses developed in the two rods are equally provided, is equal to
detailed solution
Correct option is C
Thermal stress =YαΔθIf thermal stress and rise in temperature are equal, then Y∝1α⇒Y1Y2=α2α1=32Similar Questions
