$15\mathrm{.}2$ Combined Loading

A compressed air tank has $250-mm$ outside diameter with $8-$mm thick walls. It is fitted with a collar where a horizontal force $P=40-kN$ is applied at $B(150-mm$ from the tank centerline$).$ The gage pressure inside the tank is $5$ MPa $.$

Determine the state of stress at point $L($on the outside surface of the tank, $600$ mm below point $B).$
