. American school of correspondence; a technical school for mechanics giving exclusive attention to steam and electrical engineering and the construction and operation of machinery. s parallel to the base. It is used for moving greatweights short distances, and the law is the same as for the corre-sponding inclined plane. A common method for moving bodies isto place two similar wedges as in Fig. 33 with theirthin ends overlapping under the load, simultaneousblows of approximately equal force being struckupon their heads. In this case the same force mustbe used upon each wedge as though only one wereused. But since the power is double and as theweight remains the same, the distance the body ismoved is twice as great as if there were but onewedge. Another common use of the wedge is forsplitting timber, as is illustrated in Fig. 32. Thelonger the wedge for a given thickness the greaterthe gain in intensity of power. Let ABC, Fig. 34, represent a wedge, F the force against whichit acts, and R the reaction equal to the force F. Suppose now thata blow is struck against BC so that the wedge is driven in a dis-tance equal to the distance between the two dotted lines. The.
