Hey Folks, my question is related to language in Sec VIII, Div 1, Apx 13, 13-4(k). This para speaks of moments of inertia calculated on a unit-width basis: I = b*t^3 / 12, with b = 1.0. The direction of dimension b is not formally defined in sketches or nomenclature so far as I know.
Given that the MOI is used to calculate bending stress in the side plates, I have always reasoned that b is in the vessel length direction, or looking at, say, Fig 13-2(a)(1) for example, normal to the plane of the figure.
I have recently had cause to explain my interpretation but I have no real confirmation. I’m asking myself “How do you know that?”
What say you?
TIA
The problem with sloppy work is that the supply FAR EXCEEDS the demand
