Page 290 - Majesty to inquire into the subject of weights and measures, that a cubic inch of distilled water weighed in air by brass weights at the temperature of 62 degrees of Fahrenheit's thermometer, the barometer being at 30 inches, is equal to 252 grains, and 456 thousandth parts of a grain...
Page 312 - Ibs. by the cube of the length in feet; divide the product by 32 times the tabular value of E, multiplied into the given deflection in inches ; and the quotient is the breadth multiplied by the cube of the depth in inches.
Page 311 - When the beam is uniformly loaded throughout its length, the result must be doubled, ie it will support double the weight.
Page 309 - 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...
Page 309 - If a beam 2 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, beams of the same depth are to each other as their breadths: — again, If a beam two inches deep, and...
