Determine $($a$)$ the shear force for sections to the left of $B$ and to the right of $B$ and $C,$ and $($b$)$ the bending moments for sections at $A,B,C,$ and $D$ for the beam with the overhang shown.

Sketch and label the shear$-$force and bending moment diagrams for the beam shown.

Determine the maximum tensile and compressive bending stress for the cantilever beam with concentrated loads $P_1=4$ kip and $P_2=6$ kip cross and section shown.
