"But how much do you know of prismoidal formulae, or logarithmic secants? not to speak of segmental ordinates, or the cycloidal calculus; or even of adiabatic expansion, or torsional resistance, or the hydrostatic paradox, or the coefficient of friction? Now, these things are the very A B C of mechanics, as you'll find to your utter confusion."
This water should soon fill the stem completely, forming a continuous column of liquid which, by its hydrostatic pressure, produces a gentle suction, thus materially promoting the rapidity of filtration. Unless the filter allows free passage of water under these conditions, it is likely to give much trouble when a precipitate is placed upon it.
"Of course something may develop when you take your craft high in the air, and discharge the guns there," said the lieutenant. "In a rarefied atmosphere the recoil check may not be as effective as at the earth's surface. But, in such case doubtless, you can increase the strength of the springs and the hydrostatic valves." "Yes, I counted on that," Tom explained.
The spongy nature of this meshwork affords free access of aqueous to the venous sinus of Schlemm, thence by tributaries into the supra-choroidal space and anterior uveal venous system. Fuchs's iris cripts afford direct access of aqueous to the veins of the iris. Furthermore, two simple principles are taught by physics: Fluids are incompressible and they seek the lowest hydrostatic level.
In view of the fact that such bomb-dropping is exceedingly inaccurate, and that the charges carried are relatively small, this form of attack ordinarily would not be very dangerous for the submersible. Surface craft have also employed large charges of high explosives, which are caused to detonate by hydrostatic pistons upon reaching a certain depth.
In addition to the work which caused him so great misfortunes he published Discorso e Demonstr. interna alle due nuove Scienze, Delia Scienza Meccanica , Tractato della Sfera ; and the telescope, the isochronism of the vibrations of the pendulum, the hydrostatic balance, the thermometer, were all invented by this great leader of astronomical and scientific discoverers.
Where the strata are inclined at a considerable angle, the freezing of a thin film of water over a large interstratal area might occasion a slide that should cover miles with its ruins; and similar results might be produced by the simple hydrostatic pressure of a column of water, admitted, by the removal of the covering of earth, to flow into a crevice faster than it could escape through orifices below.
The ground swayed and rocked, and a number of the spectators staggered back. It was like the blast of a hundred thunderbolts. The gun shook as it recoiled from the shock, but the wonderful disappearing carriage, fitted with coiled, pneumatic and hydrostatic buffers, stood the strain.
Not I. Do you think I don't understand what my friend, the Professor, long ago called the hydrostatic paradox of controversy? Don't know what that means? Well, I will tell you. You know, that, if you had a bent tube, one arm of which was of the size of a pipe-stem, and the other big enough to hold the ocean, water would stand at the same height in one as in the other.
It does not appear, however, that any important use was made of the strange vehicle; but the man who invented it put his mechanical ingenuity to other use with better effect. It was he who solved the problem of oblique forces, and who discovered the important hydrostatic principle that the pressure of fluids is proportionate to their depth, without regard to the shape of the including vessel.
