Hoping some one here understands these equations, I sure don't.
Wanting to find out the ID change of an aluminum tube 1"OD X 3/4"ID X 2" length say at 20ºf/-6.6ºc compared to 165ºf./74ºc
Wanting to find the OD change of a solid steel shaft 3/4" OD X 12" length say at 20ºf/-6.6ºc compared to 165ºf./74ºc
Both dimensions are originally dimensioned at 70ºf/21ºc
Coefficient of Linear
Thermal Expansion (a)
Steel:
7.0 x 10-6 in/in-deg F
3.0 x 10-6 m/m-deg C
Aluminum:
13 x 10-6 in/in-deg F
23 x 10-6 m/m-deg C
Thanks for any input
