[ \fracKLr, \quad r = \sqrt\fracIA ] For a pin-jointed truss in equilibrium at each joint:

[ \tau_\textmax = \frac3V2A ] Critical load for a slender, pin-ended column: structural analysis formulas pdf

(radius (r)): [ I = \frac\pi r^44, \quad A = \pi r^2 ]

Where: ( V ) = shear force, ( Q ) = first moment of area about neutral axis, ( I ) = moment of inertia, ( b ) = width at the point of interest. Effective length factors (K): [ \fracKLr, \quad r

[ \tau_\textavg = \fracVQI b ]

Distribution factor at joint: [ DF = \frack_i\sum k ] Rectangle (width (b), height (h)): [ I = \fracb h^312, \quad A = bh ] Effective length factors (K): [ \fracKLr

[ \sigma_x = -\fracM yI ]
