Página 302 - The distance between the supports of a beam of Riga fir is 16 feet, and the weight it must be capable of sustaining in the middle of its length is 8000 Ibs., with a deflection of not more than...
Página 299 - If a beam be supported at both ends and loaded in the miMle, its length being I — 2 c, its proof deflection is the same with that of a beam of the same transverse dimensions and of the length c, fixed at one end and loaded at the other ; and its proof load is double of that of the latter beam ; therefore its resilience is double of that of the latter...
Página xviii - SICKNESS, and for the febrile affection incident to childhood it is invaluable,— On the value of Magnesia as a remedial agent it is unnecessary to enlarge ; but the Fluid Preparation of Sir James Murray is now the most valued by the profession, as it entirely avoids the possibility of those dangerous concretions usually resulting from the use of the article in powder.
Página 302 - Divide the weight to be supported, in Ibs., by the tabular value of E, multiplied by the breadth and deflection, both in inches; and the cube root of the quotient, multiplied by the length in feet, equal the depth required in inches.
Página 299 - TRANSVERSE STRENGTH OF BEAMS, BARS, &c. If a beam be supported at both ends, and loaded in the middle, it will bend (which is called deflection) ; and if the load be increased, it will break (which is called fracture). — If a beam two inches deep and one inch broad support a given weight, another beam of the same depth, and double the breadth, will support double the weight ; hence...
