B$.$ Assuming an increasing uniform load is applied on beam $1$ and beam $2$ below until failure, do the following:

I. Sketch the bending moment and shear force diagrams

II$.$ Sketch the locations along the beam where bending reinforcement is required

III. Sketch a layout of the shear reinforcement along the beam, indicate the regions where stirrups are spaced most closely

IV$.$ Draw the expected crack pattern due to shear and bending demands. Identify the areas of flexure$-$shear and web$-$shear cracks.

Beam $1$

Beam $2$
