Required Information Find the second moment of area, the location of the neutral axis, and the distances from the neutral axis to the top and bottom surfaces. Consider that the section is transmitting a positive bending moment about the $z$ axIs, $M_Z$, where $M_Z=10\mathrm{kIp}?\mathrm{In}$ If the dimensions of the section are given in Ips units, or $M_Z=1.13\mathrm{kN}?\mathrm{m}$ If the dimensions are In SI units. Determine the resulting stresses at the top and bottom surfaces and at every abrupt change in the cross section. From the figure The area is determined to be ${\mathrm{in}}^2$ The distances from the neutral axis to the top and bottom surfaces are determined to be in and $\mathbf{x}\ln$. The second moment of area is determined to be * ${\ln }^4$.
