الصفحة 4 - The science of Politics bears in one respect a close analogy to the science of Mechanics. The mathematician can easily demonstrate that a certain power, applied by means of a certain lever or of a certain system of pulleys, will suffice to raise a certain weight. But his demonstration proceeds on the supposition that the machinery is such as no load will bend or break. If the engineer, who has* to lift a great mass of real granite by the instrumentality of real timber and real hemp, should absolutely...
الصفحة 8 - Mechanical knowledge may obviously be distinguished into three kinds : purely scientific knowledge, — purely practical knowledge — and that intermediate knowledge which relates to the application of scientific principles to practical purposes, and which arises from understanding the harmony of theory and practice. The objects of instruction in purely scientific mechanics and physics are, first, to produce in the student that improvement of the understanding which results from the cultivation...

الصفحة 5 - ... which he finds in treatises on dynamics, and should make no allowance for the imperfection of his materials, his whole apparatus of beams, wheels, and ropes would soon come down in ruin, and, with all his geometrical skill, he Would be found a far inferior builder to those painted barbarians who, though they never heard of the parallelogram of forces, managed to pile up Stonehenge.
الصفحة 598 - ... the weight of liquid displaced must be equal to the weight of the floating body, and the centre of buoyancy must be in the same vertical line with the centre of gravity of the floating body.
