Pāgina 379 - 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 172 - 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 177 - And when the breaking-weight is so great as in the case of short pillars, it may be considered that no part of the strength of the pillar is applied to resist flexure.
Pāgina 176 - Eider's theory, that the strength of pillars to bear incipient flexure is directly as the fourth power of the diameter, and inversely as the square of the length.
Pāgina 147 - EXPERIMENTAL RESEARCHES on the STRENGTH and OTHER PROPERTIES of CAST IRON ; with the Development of New Principles, Calculations Deduced from them, and Inquiries Applicable to Rigid and Tenacious Bodies generally. By the EDITOR.
Pāgina 302 - 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 186 - 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.
Pāgina 163 - These results were obtained direct from the unerring voice of nature. The first of these laws was announced by Dr. Robison, as a general law of nature, on the simple authority of a few experiments on the slips of gum caoutchouc and the juice of the berries of the white bryony, of which a single grain will draw to a thread two feet long, and again return to a perfectly round sphere. (See " Manchester Memoirs,
Pāgina 169 - ... 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.
