Not illustrated. 1903 edition. Excerpt: ...of the profile of the hull can be noted on the plate. VESSEL E. CONDITION I. PLATE 62. 41. The vessel is shown in the normal load condition with the cargo holds forward and aft filled with a uniformly distributed homogeneous cargo which gives a displacement of 17050 tons on the draught of 28'. The curve of buoyancy is drawn in accordance with the standard system as shown by B B B, and the curve of weight, plotted on the satne scale, is represented by W W W on the plate. The common horizontal scale is that given byL/20 or 530/20 = 1" = 26.5," and the vertical scale of weight and buoyancy is given by D/3L or 17050/3 x 530 = 1"--10.7 tons. 42. The curve of shearing stress, S S S, is plotted from the integration of the uncommon parts of the curves of weight and buoyancy, to the scale of D 30 or 17050 30 = 1" = 568.3 tons. This curve is then integrated and gives the curve of bending stress, M M M, -which is plotted to the scale D x L 200 or 17050 x 530/200 = 1" = 45181.4 foot tons. The maximum ordinate of this curve of bending stress occurs at about the middle of the length and records a stress of 128766.9 foot tons, which is quite moderate in a vessel of this type and dimensions. VESSEL E. CONDITION 2. PLATE 63. 43. The engine and boiler compartments of the vessel are now taken as bilged and open to the sea. The ship then settles a mean depth of 3.39', and trims 2.79' by the stern, in which position the displacement and position of the center of buoyancy for equilibrium are regained. The curve of weight, W W W, is unchanged, but the curve of buoyancy is broken up, as shown by B B B on the plate. The irregular form of the curve of buoyancy over the bilged section is that given by the displacement of the engine, boiler, coal, ...
