Beam Shear Stress

Beam 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	\(\large{\frac{lbf}{in^2}}\)	\(\large{Pa}\)
