For the midships section shown, the deck thickness is $1$ inch; the sides are $\frac{1}{2}$

inches thick; the bottom is $0\mathrm{.}6$ inches thick, and the total effective area of the section

is $768i{n}^2.$ The location of the neutral axis is $11\mathrm{.}25$ ft above the baseline. The section if

for a ship whose maximum bending moment is $9500$ ft$-$LT $,$ miships. The moment of

inertia for the section is $8,611,230$ in ${?}^4.$ If a deck, $\frac{1}{2}$ inches thick, is added to the full

width of the ship, $7$ ft above the baseline, what will be the resulting values of:

a$.$ Moment of Inertia for the section.

b$.$ Position of the neutral axis.

c$.$ Bending stress in the bottom plating.

d$.$ Suitability of AH$36$ marine grade steel; assuming a safety factor of $1\mathrm{.}33.$
