compared to its diameter at 68oF. What is the temperature of the copper sheet in the sun?coefficient of linear expansion of copper 17 x 10^-6
The displacement of a any linear behaving material due to change in temperature is: delta alpha * deltaT * L where alpha is the coefficient of thermal expansion, deltaT is the change in temperature, L is the characteristic length, and delta is the displacement. For the hole in a sheet of copper, the characteristic length is the diameter of the hole: (delta/L) 0.00153 17*10^-6 * (68 - x) x -22.0 degF
