A vessel with its cross section shown in the figure below is acted upon by a vertical

bending moment of $300MNm.$ The vessel is at rest in still water but heels ${20}_{-}$

degrees due to transverse shift of cargo.

a$)$ Calculate the maximum bending stress in the hull girder in the heeled

condition.

b$)$ At what angle would the bending stress be most severe?

$[$ at deck corner$)$; $21\mathrm{.}96$ degrees $]$
