diminishes. 235. Wedge on the Principle of Work. Let ABC (Fig. 182) be an isosceles wedge, and let the power act-ing against the resistances Q and R(= 2R) force the wedge uniformlyin a distance equal to DC Thework done by P is P.DC Theeffective distance through whichI the resistance has been… … 236.] WEDGE. 245 resistance due to friction is enormous. The wedge,however, is an important instrument; it appears in manycutting tools, such as the knife, chisel, axe, plane, andso on. It should be noticed that in the case of the plane,for example, if used for cutting soft wood, the angle issmall…
