To determine the distribution of transverse shear stress in the cantilever beam at B, we will:
1. Draw the shear-force and bending-moment diagrams for the cantilever. From these diagrams, we will determine the internal shear force V at the point of interest.
2. Determine the section properties for the tee shape. Since the shape is not symmetric about a horizontal axis, we must first determine the location of the centroid. Then, we will compute the moment of inertia and Q. To create the stress distribution, we must calculate Q at a number of y coordinates.
3. The transverse shear stress τ will be computed with the transverse shear stress formula. The stress will be computed at a number of y coordinates. After computing τ at various key locations, the shear stress distribution over the depth of the tee shape can be drawn.
