A bolt is passed through a pipe and a nut is just tightened. Coefficients of linear expansion for bolt and pipe material are `alpha_(b)` and `alpha_(p)` respectively. If the assembly is heated then:

Two rods of lengths L_(1) and L_(2) are welded together to make a composite rod of length (L_(1)+L_(2)) . If the coefficient of linear expansion of the materials of the rod are alpha_(1) and alpha_(2) respectively. The effective coefficient of linear expansion of the composite rod is

A composite bar of length L=L_(1)+L_(2) is made from a bar of material 1 and length L_(1) attached to a bar of material 2 and length L_(2) . Find the effective linear expansion alpha of this bar.The coefficinets of linear expansion of the material of the rods are alpha_(1) and alpha_(2) respectively.

The length of two metallic rods at temperatures theta are L_(A) and L_(B) and their linear coefficient of expansion are alpha_(A) and alpha_(B) respectively. If the difference in their lengths is to remian constant at any temperature then
