I start with a piece of 300 series stainless steel that measures 1foot (12.000 inches) in outside diameter with 3in. (3.000 inch) hole in center. The starting temperature of the steel is 120 degrees fahrenheit.
When the piece of stainless steel cools to 70 deg fahrenheit what is outside diameter measurement which was previously recorded at 12 inches? What is the new inside diameter?
What is the coefficient of expansion formula for this observation? And notice that the temperature is measured in fahrenheit.
You must show your work.

The 300 series is shown here
http://www.assda.asn.au/asp/index.asp?pgid=17971
to have a COE of 17.6 um/m/C. in this temperature range.
this converts to 9.778 in F (which are 5/9 the size of C)
and converting to uniform units (10^6 um per meter)
(moving decimal point 6 places.)
0.000009778 inches per inch (or m/m or ft/ft)
so the new OD will be 12" - (12*50*0.000009778)
the new ID will be 3" -(3*50*0.000009778)
