Question $2$: Consider the shear force and bending moment diagrams obtained in Problem $1.$ The beam has the solid circular cross section shown in the figure with diameter $d=300mm.$

a$)$ Determine the maximum flexural stress, in magnitude, and the location $(x,y)$ where it occurs.

b$)$ Sketch the flexural stress distribution on the cross section identified in part $($a$).$

c$)$ Determine the maximum transverse shear stress and the location $(x,y)$ where it occurs.

Please Include the sketches in the solution.
