V R M R Four spheres are rigidly attached to a crossbar frame of negligible weight A couple moment M is applied as shown by the curved arrow In addition a couple of forces R is applied to the centers of spheres B and D as shown Also a couple of forces Q is applied to the centers of spheres A and C as shown The direction of the forces relative to the crossbar frame always remains as shown
