Pāgina 377 - Babylon, making its course to the south, the palaces lie the one on the east, and the other on the west side of the river; both built at exceeding costs and expense.
Pāgina 310 - ... That gravity should be innate, inherent and essential to matter, so that one body may act upon another at a distance through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity, that I believe no man who has in philosophical matters a competent faculty of thinking, can ever fall into it.
Pāgina 443 - ... on the collection of a great number of workmen together, who lived in common with a few women suffering under blennorrhagia.
Pāgina 170 - Mr. Hodgkinson proceeds to describe the methods by which his experiments were made, and derives from them the following nonelusions : 1. All rigid bodies are possessed of some degree of elasticity, and among bodies of the same nature the hardest are generally the most elastic.
Pāgina 174 - Euler1s theory, that the strength of pillars to bear incipient fleocure is directly as the fourth power of the diameter, and inversely as the square of the length.
Pāgina 300 - The use of this vessel was abandoned, not from any fault in her construction or working, but because the Directors of the Forth and Clyde Canal feared that she would damage its banks.
Pāgina 128 - K heat of a stated weight of vapour, than from any direct experiments on the density of vapour made up to that time. This conclusion has been verified by the recent experiments of Messrs. Fairbairn and Tate. With the assistance of some excellent tables in Rankine's " Steam Engine and other Prime Movers...
Pāgina 166 - Moseley1s concise and able exposition of the experiments and reasonings of Mr. Hodgkinson by which he established the best form of castiron beam. " Since the extension and the compression of the material are the greatest at those points which are most distant from the neutral axis of the section, it is evident that the material cannot be in the state bordering upon rupture at every point of the section at the same instant, unless all the material of the compressed side be collected at the...
Pāgina 184 - The value of (/) the strain upon a square inch at the top or bottom of the tube is constant in material of the same nature, while it varies from 19, 14, to 7! tons when the thickness of metal varies from '525, '272, to '124 of an inch. The determination of (/) is the chief obstacle to obtaining a formula for the computation of the strength of tubes of every form.
Pāgina 167 - ... collected into two unequal flanges joined by a rib, the greater flange being on the extended side, and the proportion of this inequality of the flanges being just such as to make up for the inequality of the resistances of the material to rupture by extension and compression respectively. Mr.
