In the system above, two spheres of weight Q and W are in contact with each other at point C. If there is no friction at the contact points A, B and C of the spheres and the spheres are in balance without moving, calculate the contact forces A, B, C? Determine the force P that keeps the system in balance?Note: Q=40kN, W=80kN
