Determine:

Part $1$: moment of inertia for the cross$-$section about the z centroidal axis: I$\_$z in in$^4$

Part $2$: The maximum value of the first moment of the area for the cross$-$section: Q$\_$max in in$^3$

part $3$: The maximum allowable shear force in beam: V$\_$max in lb

Part $4$: Maximum allowable distributed load: W$\_$max in lb$/$ft

Part $5$: Shear force in the beam at x$=63.$ assuming the beam is subjected to the distributed load calculated in part $4$: V in lb

Part $6$: The first moment of the area H: Q$\_$H in in$^3$

Part $7$: The shear stress at H assuming the beam is subjected to the distributed load W$\_$max calculated in part $4$: T$\_$H in psi

Part $8$: The maximum moment magnitude at any location in the beam when the beam is subjected to the distributed load W$\_$max calculated in part $4$: M$\_$max in lb$-$ft

Part $9$: The maximum tension bending stress at any location in the beam when the beam is subjected to the distributed load W$\_$max calculated in part $4$: O$\_$x in psi
