Hi, I have just started a HND in Aeronautical Engineering and its been awhile since I have done any maths, need help with finding the second moment of area using Euler's theory!(adsbygoogle = window.adsbygoogle || []).push({});

I have Euler's equation : Force (P)= (pi squared (pi2)) * (modulus of elasticity (E)) * (second moment of area (I)) / (effective length squared (L2))

I then got I = P*L2/pi2*E (is that correct?)

P = 170KN - factor safety of 3 needed - 510KN

L = 8m

E = 200 GPa

I am struggling with the units, I need I in cm4 and can't work it out!

Thanks
