11. The tensile and compressive force lines are symmetrical and are denser at the beam s edge. 12. Limbs are made of composite materials and are capable of taking high tensile and compressive forces . 13. When tensile specimens are initially placed into testing grips, they can be subjected to small compressive forces . 14. The discs cushion the spine from compressive forces , but are weak to pressure applied during rotational movements. 15. The failure actually occurs because compressive forces make the top of the beam want to spread sideways. 16. The nylon insert locks the nut by friction against the screw under the applied radial compressive force . 17. The fracture is reduced by pushing the iliac bone inwards towards each other using bilateral compressive force . 18. When a compressive force is applied in the knee joint, a tensile force is transmitted to the menisci. 19. Ovda Regio has ridges running in two directions, suggesting that the compressive forces are acting in several directions. 20. Compressive forces caused by the Laramide orogeny were followed by some minor stretching as a new equilibrium was established.
