Dear All,

I'm a student of physics and I have two Q.

First, When the temperature of steel tube is changed, How can I calculate the change of outer diameter and inner diameter of tube?
the oute diameter is 40mm, the inner diameter is 30 mm, the length of
tube is 100mm

Next, When the temperature of steel tube is changed, How can I calculate the change of length of tube? the oute diameter is 40mm, the inner diameter is 30 mm, the length of tube is 300mm

Best Regards, Aref, snipped-for-privacy@yahoo.com
