SHEARING STRESS IN A BEAM—
EXACT METHOD
Calculate the maximum shearing stress in a W18 55 beam at a section where the verti-
cal shear is 70 kips (311.4 kN).
Calculation Procedure:
1. Record the relevant properties of the member
The shearing stress is a maximum at the centroidal axis and is given by v VQ/(It).
The static moment of the area above this axis is found by applying the properties of the
