    hi there , i'm asking for help with this one! I should solve that problam through energy method.
    Given single force Q(not shown in the picture) on the edge of the cantilever(the right-end of the beam), what i'm looking for - The critical P(axial force) that beam can absorb. the answer is in Euler form.

    any suggestions would help!

    sorry for the poor english.

    You must be given the beam properties. Then it's fa/Fa + fb/Fb = 1. With appropriate safety factors. I assume Q is applied perpendicular to beam. Please show attempt.
