Seite 23 - ... been checked at once, had the great truth been generally understood, that no form or combination of machinery ever did or ever can increase, in the slightest degree, the quantity of power applied. Ignorance of this is the hinge on which most of the dreams of mechanical projectors have turned.

Seite 23 - Hence the common error in supposing that they generate force, or have a sort of innate power for saving labour ; whereas, neither simple machines nor mechanic powers save labour, in a strict sense of the phrase. Why, then, are these machines advantageous ? Because they allow a small force to take its time to produce any requisite magnitude of effect. Thus, one man's effort, or any small power, which is always at command, by working proportionally longer, will answer the purpose of the sudden effort...
