11. :Remember that concrete is strong under compression . 12. The joint is fitted under compression to keep it together; if the glue fails, the joint still holds. 13. Wood initially dries from the shell ( surface ), shrinking the shell and putting the core under compression . 14. With the new design, the lower ball joints were now under compression , thus eliminating the premature wear issue. 15. To construct his glass sculptures, Lane exploits the strength of glass under compression and its qualities of luminosity. 16. Solem examined the fundamental nature of foams under compression and showed a general hyperbolic stress-strain relation ( 1999 ). 17. A strut is a bracing component stiff enough to resist these forces whether they place it under compression or tension. 18. To keep them under compression , says Szulgit, you need a catenary arch, which is slightly higher than it is wide. 19.
