The mechanical properties of DNA under compression have not been characterized due to experimental difficulties in preventing the polymer from bending under the compressive force.

The structure is kept under compression by the weight of the covers, sometimes supplemented by a heavy weight hung from the center of the roof.
33.
A wire is a bracing component able only to resist tension, going slack under compression, and consequently is nearly always used in conjunction with struts.
34.
This is because under compression, most materials will experience trivial ( lattice mismatch ) and non-trivial ( buckling ) events before plastic deformation or fracture occur.
35.
The surface strain of the thin layer places the harder metal under compression, so that when the entire composite is sintered the rupture strength increases markedly.
36.
The oxide layer puts the surface of the metal in tension because the oxygen atoms squeeze into the lattice, and the oxygen atoms are under compression.
37.
Cetane ignites very easily under compression; for this reason, it is assigned a cetane number of 100, and serves as a reference for other fuel mixtures.
38.
Fault plane solutions also played the key role in the discovery that the deep earthquake zones in some subducting slabs are under compression, others are under tension.
39.
This poststressing places the concrete under compression a condition under which it is extremely strong in bending and so will not crack under adverse soil conditions.
40.
Since concrete is best under compression, it would be better to use it, say, for the pillars themselves, and use some other material for the table surface.
