s, 26. Algebraically.—Take the same system of forces as before, Fig. 14. Resolve each force into horizontal and vertical components (any twodirections at right angles will do as well), or along theaxis of Xand the axis of F respectively. These com-ponents form a system equivalent to the given… … V(^ hor. comp.) -|- (2 vert. comp.). The tangent of the angle between R and the axis of F is 2 hor. comp. , , „ . , . , • given by -^^^ —, and thus R is determmed in ■2: vert. comp. amount and direction. Its point of application is A as before, whence it becomes fully known. APPLICATION OF THE LAWS…
