BC P k A k k FA. The forces applied by the springs and the applied forces on point P are in equilibrium. B. The extension in each of the springs is governed by F=kδ C. The extensions and rotations of the springs will allow them to remain attached at P 1. A only 2. B only 3. C only 4. A and B only 5. B and C only 6. A and C only 7. A, B and C 8. None of the above 9.
