Σελίδα 21 - ... is equal to the sum of the moments of the forces which tend to turn the body in the opposite direction about the same point.
Σελίδα xviii - The unit of force is that force which, acting for one second on a mass of one gramme, gives to it a velocity of one centimetre per second.
Σελίδα 11 - The work done by a force is measured by the product of the force into the distance through which that force moves in its own direction.
Σελίδα 256 - ... the ratio of the mass of a given volume of the substance to the mass of an equal volume of water, in which case it is equal to the specific gravity. In its application to gases, the term
Σελίδα 147 - Ibs. 6. In a crane there is a train of wheelwork, the first pinion being driven by a lever handle ; and the last wheel being on the same axis as the chain barrel of the crane. The wheelwork consists of a pinion of 1 1 gearing with a wheel of 92, and of a pinion of 12 gearing with a wheel of 72, the diameter of the barrel being 18 inches and that of the circle described by the end of the lever handle being 36 inches ; find the ratio of the pull to the weight raised, friction being neglected.
