Handy Formula Sheet

Use units: Force (N), Length (mm), Stress (MPa) 

E = Young's Modulus or Mod of Elasticity (MPa). Steel = 200,000 MPa

I = 2nd Moment of Area or Area Moment (mm4). Can calculate using SolidEdge sketch.

BUCKLING

Maximum load in compression might be smaller than expected by the standard calculation (f=F/A) due to buckling. If column is "slender" it is likely to buckle.
