139. A combination of levers is sometimes used, but more often for the purpose of magnifying small motions than for exerting great force; that is, for increasing the factor s in the product work at the expense of the factor F. In fig. 58 the motion of the screw is magnified, the pointer describing a considerable arc for one turn of the screw. (p. 138) |
