WebIt is clear from the above notes that for a beam subject to shear loading and bending the maximum shear stress is at the neutral axis and reduces to zero at the the outer surfaces wher y 1 = ± c . For this section the maximum stress is equal to 3/2 the average shear stress = S / A . The maximum shear stress in other sections are shown below. WebIf the cross section is symmetrical about the horizontal axis, then the neutral axis is halfway between the top and bottom. However, for non-symmetrical beam, such as a "T" cross section, the neutral axis is not halfway between the top and bottom, and needs to be determined before the bending stress equation can be used.
