1. :: : Under compression Hydrogen can be a liuquid at room temperature. 2. Upon cooling, the exterior part contracts, putting the interior frame under compression . 3. The heated material flows more easily in tension, but cools and stiffens under compression . 4. Plant stems and other three-dimensional plant structures do not preserve as well under compression . 5. Since the concrete is always under compression , it is less subject to cracking and failure. 6. Motorcycle suspensions are designed so that the springs are always under compression , even when fully extended. 7. Instead, you have to keep it under compression . 8. It is therefore not economical to replace glass fiber components under compression with carbon fiber components. 9. The Uni-Trak system was designed to provide a progressively stiffer damping and spring rate under compression . 10. The two posts are under compression from the weight of the lintel ( or beam ) above.
