Questions $4-8$

For the beam and loading shown below, draw a free$-$body diagram $($FBD$)$ of the beam and solve

for the reactions at points A and B$.$ Then draw a shear and moment $($V&M$)$ diagram for the

beam. Use the beam bending sign$-$convention for V&M$.$ Ignore the self$-$weight of the beam.

Question $4(10$ points$)$ What is the maximum positive $(+)$ shear force, V$,$ in the beam?

Question $5(10$ points$)$ What is the maximum negative $(-)$ shear force, V $,$ in the beam?

Question $6(10$ points$)$ What is the maximum positive $(+)$ bending moment, M $,$ in the beam?

Question $7(10$ points$)$ What is the maximum negative $(-)$ bending moment, M $,$ in the beam?
