Hi Everyone,
Recently I received some help in the Forum for a compact writing of a formula:
https://en.smath.com/forum/yaf_postst23760_Long-Formula-Writing.aspx
The problem behind this formula could be helpful for many structural engineers, to obtain the buckling length of a member having known ends restraints.
I mention that this formula cover both "say and non sway" buckling cases.
The backgrounds of the formula are obtained from a very interesting German book:

I put the application in the appended file:
Buckling Length.sm (1 МиБ) скачан 104 раз(а).
Any suggestions or critics are welcomed.
Regards,
Ioan
