Initial

Consider the $"$I$-$Section" with the specifications and $\_-$applied load of $F=12$kip, as shown. Determine nornal stresses, ${}_n,$ at the key points $A,B,C,D$ and E $($ C is the centroid$)$; Dimensions are in inches.

Point A: F$$

$m=\frac{115}{\text{I}}$

$=\frac{120(10)}{123\mathrm{.}5}=120$ kies.$in={4\mathrm{.}85}^{155i}-3$

Point B:

$=\frac{120}{123\mathrm{.}5}=4\mathrm{.}85$ksi$-3$

$A=7\mathrm{.}46i{n}^2$

$I_x=123\mathrm{.}5i{n}^4$

$I_y=6\mathrm{.}79i{n}^4$
