A structural member with a rectangular cross section sipports a Problem $2(10$ points$)$

A structural member with a rectangular cross section supports a $15$kip load, as shown in the Figure. Calculate the following:

a$)$ the equivalent centric load and bending moment plus draw the FBD$,$

b$)$ the cross$-$section area and second moment of area,

c$)$ the stress at point $\backslash ($ A $\backslash ),$

d$)$ the stress at point $\backslash ($ B $\backslash ),$

e$)$ the distance between the centroidal and the neutral axis of a cross section,

f$)$ draw the stress distribution at section A$-$B$.$
