The calculations of shearing and bending stresses in the material of the structure will be dealt with later. The other result arising from these forces and moments is that there is overall deflection of the structure, i.e. the ends of the ship move vertically relative to centre. When the ends move upwards relative to the centre the ship is said to "sag" and the deck is in compression while the bottom is in tension. If the reverse is the case then the ship "hogs" with the deck in tension and the bottom in compression. |
