I'm guessing wjat you really meant to write tis this:



FYI - for future reference the convention for signifying a power is to use tke carat symbol ^, so x^2 would mean "x squared."

This formula looks a variation of the Euler critical load equaton, with the exception that you've placed an x^2 where there should be pi^2. No matter - to make 'I' the subject you need to do a series of operations that leaves 'I' by itself. First multiply both sides by the denominator of the right had side; this causes the L^2 term on the right to cancel:



Then divide both sides by x^2E:

Thank you, excellent help, much appreciated.
