187. Let the line Frepresent the magnitude and di-rection of a force acting to move the body B on theline CD; then the line a represents a part of Fwhich presses the body B against CD, and the lineb represents the magnitude of the force whichactually moves the body B. b = ^F — tf, b = Fcos.v. … 188. F : W = h : b = sin.r : cos.v : Wh = tan.v. F = = Wtan.v. F*-F. Fb F W= ~r = r— - F cot-v-h tan.-y
