Beam Shear Stress

on . Posted in Classical Mechanics

sagging hogging 1Beam shear stress, abbreviated as \(\tau\) (Greek symbol tau), is the horizontal shear stress of a beam.


Beam Shear Stress formula

\(\large{ \tau = \frac{ V \; Q }{ I \; t }  }\)
Symbol English Metric
\(\large{ \tau }\) (Greek symbol tau) = shear stress \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ Q }\) = first moment of area \(\large{ in^4 }\) \(\large{ mm^4 }\)
\(\large{ t }\) = material thickness perpendicular to shear \(\large{ in }\) \(\large{ mm }\)
\(\large{ I }\) = moment of inertia of entire area cross-section \(\large{ in^4 }\) \(\large{ mm^4 }\)
\(\large{ V }\) = total shear force at the point of location \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
