The question we have to put to the steel makers is, What " are our prospects of obtaining a material which we can use without such delicate " manipulation, and so much fear and trembling ? We...

Page 173 - ... duty. It is probable that 2, 3, and 4 of the above list are all very nearly proportional to the useful thrust; 6 is probably nearly proportional to the square of the number of revolutions, and thus at least at the lower speeds approximately to the useful thrust; 5 probably remains constant at all speeds, and for convenience it may be regarded as constant though perhaps in strict truth it should be termed "initial friction.
Page 139 - We want a perfectly coherent and " definitely carburized bloom, or ingot, of which the rolls have only to alter the form "in order to make plates with qualities as regular and precise as those of copper and " gun metal, and we look to the manufacturers for it.

With this view, ever since I have entered into such investigations, I have invariably converted the horse-power term to a force term by simply dividing it by a speed factor, and, as shaping the reduction into its most natural and opposite form, I have adopted as the divisor, the speed of the propeller, expressed, not by its revolutions nakedly, but by its revolutions x its pitch, that is to say, the virtual travel of the force...
