Replace the two wrenches and the force, acting on the pipe assembly, by an equivalent resultant force and couple moment at point O. 11. 5. Replace the force system by a wrench and specify the magnitude of the force and couple moment of the wrench and the point where the wrench intersects the x–z plane. 6. Replace the three forces a cting on the
equivalent resultant force and couple moment acting at A and then the equivalent single force location measured fromA 1) Sum all the x and y components of the forces to find F RA. 2) Find and sum all the moments resulting from moving each force component to A. 3) Shift F RA to a distance d such that d = M RA /F Ry
4. Replace the force and couple system by an equivalent force and couple moment at point O. Solution: Sign convention: All clockwise moments are +ve, and counterclockwise moments are –ve
