For Circular section the maximum shear stress = (4/3) * Average shear stress. Therefore The ratio = (4/3) * Average shear stress/Average shear stress = 4/3.

For circular section = 4/3 or 1.33. For rectangular section = 1.5.

Maximum shear stress occurs at neutral axis and y=0. The maximum shear stress distribution is 33% more than average stress. Then 4/3.
