Problem $7$

The steel beam shown below has a box section. If the beam is subjected to the loads shown in the figure. Determine the following:

a$)$ Draw the bending moment and shear force diagrams

b$)$ The maximum shear stress in the section

c$)$ The maximum bending stress and the bending stress at point a

d$)$ Given that is $200$ MPa and is $50$ MPa calculate the safety factors available in this design for both shear and bending stress
