## Homework Statement

I am trying to determine the deformation of a beam loaded as shown in the attached picture.

where:

P=30kN

L=1m

A=0.000225m^2

E=2.22*10^5MPa

v=0.31

I=4.21875*10^9m^4

## Homework Equations

Pcr=pi^2*EI/L

=9.2435kN

where Pcr is the critical load

## The Attempt at a Solution

I assume that the deformation of the beam in the vertical direction is not simpily PL/AE as P>Pcr?

I was thinking I could calculate the horizontal deflection of the beam as it buckles and use trig to find the vertical deformation but I cannot find a way to calculate this maximum horizontal deflection. Any ideas?

Thanks in advance.
