For beam in Figure $2,$

Question $4$

Find the corresponding reaction force at point A

Question $5$

Find the corresponding reaction force at point B

Question $6$

Find the corresponding reaction force at point D

Question $6\mathrm{.}5$

Draw the shear force and bending moment diagrams accurately to use the graphical method for the beams from point $A$ to point $D$ shown in Figure and justify your drawings $($Please describe the maximum and minimum values and their exact locations$).$

Question $7$

The beam in the above Figure is made of A$-36$ structural steel with a rectangular cross$-$

section shown in the above Figure. Please determine the maximum tensile stress $[$psi$]$ in the beam $($ w$=100$l$($b$)/($f$)$t$,$L$=2$ft$,$d$=1$in$,$ and P$=400$lb$.$

Question $8$

Now rotate the cross$-$section shape by $90$ degree and find the maximum tensile stress $[$psi$]$ in the beam $($ w$=100$l$($b$)/($f$)$t$,$L$=2$ft$,$d$=1$in$,$ and P$=400$lb $).$
