Hi,
The coefficient of thermal expansion for aluminium is 23ppm/C at 20C = 0.000023m per degree in temperature (C).
Is this temperature:
(1) the temperature of the air circulating around the material in the sun,
(2) the temperature in the shade at that time of the day, or
(3) the tactile temperature of the material?
This might seem like a simple problem for Newton's love child, but I suspect I'm illegitimate. :)
