WebFor a rectangular wood beam, shear is not carried equally across the section, and has a maximum stress higher than an average stress. So when we calculate shear stress, we divide the shear force by the area of the section, but must also multiply by 1.5. Then we can check the shear stress with the allowable shear stress, from the material tables.
