WebOct 22, 2016 · So the shear area is: A s = I t Q = ( 6667) ( 10) 500 = 133.3 mm 2. Therefore the shear stress is: τ m a x = V Q I t = V A s = V 133.3 mm 2. Compare this to the resource I shared earlier and you can see that for a thick walled rectangular section the shear area (denoted by W in the resource) is: A s = 2 3 h b = 2 3 ( 20) ( 10) = 133.3 mm 2.
