$6-50.$If M$=10$kip$*$ft$,$determine the maximum bending stress in the beam. Sketch a three$-$

dimensional view of the stress distribution acting over the cross section.

Assume a shear force of $5$kips is also applied downwards on the cross$-$

section and determine the maximum shear stress in the cross$-$section. Sketch the

stress$-$distribution for both the bending and shear stress
