Las bielas ejercen dos fuerzas sobre el cigüeñal de la figura. Los cosenos directores de FA son cos θx = – 0.182, cos θy = 0.818 y cos θz = 0.545, y su magnitud es 4 kN. Los cosenos directores de FB son cos θx = 0.182, cos θy = 0.818 y cos θz = – 0.545, y su magnitud es 2 kN. Si las dos fuerzas se representan con una fuerza F que actúa en el origen O y un par M, ¿qué valores tienen F y M?
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 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?
