I need to calculate $K$ or equivalent stiffness of a beam that has a varying $I$ across its length. $I$ has been given to me as a function of $x$, or length.
I have been unable to find a proper ...

I was studying the designation of names to refrigerants.
The following is the basic formula:
R - (m - 1) ( n + 1) ( o )
where:
m = number of carbon atoms in the refrigerant
n = number of hydrogen ...
