Problem #$2$: An closed stringer$-$web cross$-$section is shown in Figure $2.$ The area of stringer #$1,$

#$2,$ and #$3$ is $10$cm$^(2).$

The cross$-$section shown in the figure is subjected to a vertical shear force V$\_($z$)=5000$N in the

positive z $-$ direction as shown. Let V$\_($y$)=0.$ The overall dimensions of the cross$-$section are given

in the figure. The shear modulus is G$=27$GPa. Assume that the thin sheets are ineffective in

bending.

aC of the cross$-$section. Specify the location of C as

horizontal and vertical distances from stringer #$2.$

bI$\_($yy$)$ and I$\_($zz$)$ y$-$z

coordinate system has its origin at the centroid C of the cross section.q$\_(12),$q$\_(23),$ and q$\_(31)$ on the closed cross section.
