Problem $7-14$: The tee section shown in Figure P$7-14$ is to carry a bending moment of $28\mathrm{.}0kN*m.$ It is to be made of steel plates welded together. If the load on

the beam is a static load, would SAE $1020$ hot$-$rolled steel be satisfactory for the plates? See Appendix A$-10$ for SAE $1020$ material properties.

A$)$ Section Area, $A=$

$m{m}^2$

B$)$ Moment of Inertia, $I_{x-x}$

$m{m}^4$

C$)$ Distance to section centroid from bottom of section$=Y=$

mm

D$)$ Section modulus, $S_{\text{b}\text{o}\text{t}\text{t}\text{o}\text{m}}=$

$m{m}^3$

E$)$ Applied bending stress at $==\frac{M}{S}=$

MPa

F$)$ Design Bending Stress for SAE $1020$ plate material $=$

G$)$ Is the SAE $1020$ hot$-$rolled steel satisfactory for the plates$=$

Pleas put the answers as shown in the picture from A to G
