Two forces are exerted on the crankshaft by the connecting rods. The direction cosines of FA are cos θx = –0.182, cos θy = 0.818, and cos θZ = 0.545, and its magnitude is 4 kN. The direction cosines of FB are cos θx = 0.182, cos θy = 0.818. and cos θz = –0.545, and its magnitude is 2 kN. If you represent the two forces by a force F acting at the origin O and a couple M, what are F and M?
