Page 156 - As the weight lost in water is to the whole, or absolute weight ; so is the specific gravity of water ' " to "the specific gravity 'of the body . 2.
Page 186 - Engine, &c. do not exceed five tons, then the gross weight to be drawn need not exceed fifteen tons, and in that proportion for Machines of still smaller weight, provided that the Engine, &c. shall still be on six wheels, unless the weight (as above) be reduced to four tons and a half or under, in which case the Boiler, &c.
Page 158 - As the tabular specific gravity of the body, Is to its weight in avoirdupois ounces, So is one cubic foot^ or 1728 cubic inches, To its content in feet, or inches, respectively.
Page 11 - MECHANICAL POWERS are certain simple instruments employed in raising greater weights, or overcoming greater resistance than could be effected by the direct application of natural strength. They are usually accounted six in number; viz. the Lever, the Wheel and Axle, the Pulley, the Inclined Plane, the Wedge, and the Screw.
Page 46 - The centres of gravity of the surface of a cylinder, of a cone, and of a conic frustrum, are respectively at the same distances from the origin as are the centres of gravity, of the parallelogram, triangle, and trapezoid, which are vertical sections of the respective solids.
Page 186 - Feet. 5th. -The weight of the Machine, with its complement of water in the Boiler, must, at most, not exceed Six Tons; and a Machine of less weight will be preferred if it draw after it a proportionate weight; and if the weight of the Engine, &c.
Page 21 - ... the power, multiplied by its distance from the fulcrum, is equal to the weight, multiplied by its distance from the same point. Prom this, simple rules may be deduced for calculation. To know the power to be applied, at a certain distance from the fulcrum...
Page 188 - ... boiler shall be cold, and there shall be no fuel in the fire-place. As much fuel shall be weighed, and as much water shall be measured and delivered into the tender-carriage as the owner of the engine may consider sufficient for the supply of the engine for a journey of thirtyfive miles. The fire in the boiler shall then be lighted, and the quantity of fuel consumed for getting up the steam shall be determined, and the time noted. " The tender-carriage, with the fuel and water, shall be considered...
Page 188 - The time of performing every trip shall be accurately noted, as well as the time occupied in getting ready to set out on the second journey. Should the engine not be enabled to take along with it sufficient fuel and water for the journey of ten trips, the time occupied in taking in a fresh supply of fuel and water shall be considered and taken as a part of the time in performing the journey.

Page 156 - ... so that the mass compounded of the two may sink together. Weigh the denser body and the compound mass, separately, both in water and out of it ; then find how much each loses in water, by subtracting its weight in water from its weight in air ; and subtract the less of these remainders from the greater. Then...
