For finding the buckling load i used Euler's equation for struts P = (Pi^2*EI)/L^2 and I got the correct answer but i don't understand what exactly I have to do in the second part of the question. Here it is:

(b) Find the buckling load if the wing is re-designed so that the strut is prevented from moving laterally in all planes at its centre.

For this my lecturer had used this equation P = (4*Pi^2*EI)/L^2

So basically 4 times the previous equation. I want to know how he got that equation and when should I use it.

Thanks!
