FORE:"And then the disaster followed suddenly. At about five o'clock a tremendous explosion shook the fort to the foundations; the powder-magazine had caught fire. It is impossible to describe the appalling results of that explosion; the entire middle-part of the fort collapsed in a stupendous cloud of flames, smoke and dust; it was an awful destruction, an immense avalanche of masses of concrete, fragments of armour, which in their fall crushed to death nearly the whole of the garrison. From this fantastical, confused mass, overwhelming clouds of suffocating smoke escaped through some crevices and holes.5. Every part laid down has something to govern it that may be termed a "base"some condition of function or position which, if understood, will suggest size, shape, and relation to other parts. By searching after a base for each and every part and detail, the draughtsman proceeds upon a regular system, continually maintaining a test of what is done. Every wheel, shaft, screw or piece of framing should be made with a clear view of the functions it has to fill, and there are, as before said, always reasons why such parts should be of a certain size, have such a speed of movement, or a certain amount of bearing surface, and so on. These reasons or conditions may be classed as expedient, important, or essential, and must be estimated accordingly. As claimed at the beginning, the designs of machines can only in a limited degree be determined by mathematical data. Leaving out all considerations of machine operation with which books have scarcely attempted to deal, we have only to refer to the element of strains to verify the general truth of the proposition.
