Web1 I'm here going to assume that by moment of area you mean the second moment of area (aka moment of inertia). That being said, the argument I'll be making is valid for the first moment as well. The planar second moment of area around an axis (say, the x-axis) is calculated by: I x = ∬ y 2 d x d y
WebCylinder Stresses - Relation To Internal Pressure - Thin-walled Assumption Thin-walled Assumption For the thin-walled assumption to be valid the vessel must have a wall … For the thin-walled assumption to be valid, the vessel must have a wall thickness of no more than about one-tenth (often cited as Diameter / t > 20) of its radius. This allows for treating the wall as a surface, and subsequently using the Young–Laplace equation for estimating the hoop stress created by an internal pressure on a thin-walled cylindrical pressure vessel: (for a cylinder) For the thin-walled assumption to be valid, the vessel must have a wall thickness of no more than about one-tenth (often cited as Diameter / t > 20) of its radius.

WebApr 11, 2024 · The thin-walled tubular deployable composite boom (DCB) can realize folding and deploying functions, and it has a good application prospect in space field. This paper investigates the folding behaviour of the tubular DCB by analytical modeling. Based on the Archimedes’ helix, the geometrical model of the DCB was established.
