Determine the effective coefficient of linear expansion

Reference no: EM1382702

Q. A composite bar made from two different materials of equal cross-sectional areas are directly attached to each other making the bar a length of L = L1 + L2.The coefficient of thermal expansion for the two materials are x1 and x2 correspondingly. Suppose the cross-section of each bar is unaffected by the heating and determine the effective coefficient of linear expansion for composite bar x in terms of L1, L2, x1, and x2.
