Help: The thermal expansion coefficient of spring.

[leo.yl.zhang]

Hi, everyone.
I am just curious about the following question:
Does the thermal expansion coefficient of a spring be the same as a slab with the same material?
Thanks very much.

Hi leo.yl.zhang, welcome to PF. The thermal expansion coefficient is a material property, so it's independent of sample size and geometry. Does this answer your question?

 

[leo.yl.zhang]

Yeah, thank you Mapes.
Here is another question:
If the lengths of a spring and a slab with the same material are equal at teperature T1, when the temperature changes to T2, the lengths still are equal. Is that correct?

 

[Mapes]

As long as they're unconstrained, yes.

 

[leo.yl.zhang]

Got it.
Thanks a billion.
