es of Rx and R2 until they intersect at O, andlet Rl and R2 act at O. Resolve Rx and R2 into components actingat O, and respectively parallel and at right angles to AB ; the com-ponents parallel to AB will be each equal to S, therefore they balanceand need not be considered further. The components… … Fio. 109.—Resultant of two parallel forces. Let the line of R, which passes through O and is parallel to P andQ, he produced to cut AB, or AB produced, in C. Then the trianglesOAC and km are similar ; hence OC Aa Act _P CA~ ac~ Ab~ S Also the triangles OBC and B/<7 are similar, therefore…
