Linear Expansion Of Solids

The increase in length of a solid subjected to rise in temperature can be represented by the equation:

   ΔL = αL₁[T₂ - T₁]

where
     L₁ = original length of bar
     L₂ = final length of bar
     ΔL = change in length = L₂ - L₁
     T₁ = initial temperature
     T₂ = final temperature
     α = coefficient of linear expansion of the material
