...a system is, the more slowly it will raise a weight. T. Certainly ; and this principle is commonly expressed by saying that what is gained in power is lost in time. This principle applies not only to pullies but to all mechanical combinations whatsoever. I shall... | |

...as that of " virtual velocities," or of "equality of moments" of the power and load, and familiarly expressed by saying that what is gained in power is lost in velocity or in time, is, calling v the velocity of the weight, and V that of the power, formulated thus: P :... | |

...point of application of the resistance, as the resistance is greater than the power. This is generally expressed by saying, that what is gained in power is lost in velocity. We see, therefore, that no power is^ or can be, gained ; the only function of a machine being to enable... | |

This is expressed by faying. that what is gained in power is lost in velocity. It is for this reason that we say there is... | |
