Thermal expansion of each dimension of a solid

  1. May 10, 2017 #1
    Hi, I am trying to work out how much each dimension of a solid (for instance an annular disc) made out of steel changes assuming that the solid is heated uniformly and is not constrained at any of its boundaries. Am I right in saying that, the linear expansion equation L = L_0 (1+ α ΔT) can be applied to each dimension individually or should the dimensions be considered related and/or the calculations are more complex?

    You are right. You can apply that expansion formula to any linear dimension.
