THERMAL DILATION FORMULA?
THERMAL DILATION FORMULA?
(OP)
Dear all,
I want to know a good formula for calculating thermal dilation or expansion of a steel shaft w.r.t temparature.
For eg:- If I have a shaft of dia. 12.7mm at room temp. then at what temp. will the shaft contract to dia. 12.5mm?
Thanks in advance.

RE: THERMAL DILATION FORMULA?
Lc = Lo x a x t
Where :-
Lc = Change in length or diameter
Lo = Original length or diameter
a = Coefficient of linear expansion
t = Temperature change
For steel a = 0.000012/deg.C
You need to find t so rearrange formula
t = Lc / (a x Lo)
For your problem temperature change needed to produce required contraction is -1312 deg.C
Not sure how to achieve this.
Hope this helps
