Explanation

In reinforced concrete sections, the shear stress distribution is parabolic above the neutral axis due to the concrete's behavior under shear, while below the neutral axis, it tends to be more uniform, resulting in a rectangular distribution. Therefore, the shear stress diagram is parabolic above and rectangular below the neutral axis.
