st common method is to usean integrator to obtain the areas and moments, about a chosen axis, of aseries of cross-sections spaced to suit one of the above-mentioned arithmeticalrules. The arrangement of an Amsler integrator when calculating stabilityis indicated in fig. 14. The plan giving… … Axis ror Moments Fig. 13. to as the assumed C.G. The assumed C.G. is for convenience generallychosen near the actual centre of gravity of the ship. The integrator is thenset so that the axis coincides with one of the radial lines. For this positionof the machine the area and moment of each section…
