Página 20 - But the true weight of a body may be found by a false balance in the following manner. First, weigh the body in one scale, and afterwards weigh it in the other ; then the mean proportional between these weights will be the true weight. For let x = true weight of the body, and W the number of ounces or pounds it weighs in the scale A, and w the ounces or pounds it weighs in the scale B ; then, by Art. 39, we shall have AcXx = BcXW, and BcXx = AcXtc. By multiplying these equations, there results, Ac...

PROP. — In a system of toothed wheels and axles, it is required to find the relation between the power and the weight, when they are in equilibrium. The power P is applied to the circumference of the first wheel a, which transmits its effect to the circumference...
