Healthy Lifestyle Compression vs Tension

Architectural principles start from the premise that all structures, including our bodies, are a balance between stretching forces and crushing forces, or briefly tension and compression. The cables that stabilize telephone poles or lift elevators are being stretched, they are subject to tension.

Crusher Wikipedia

Impact crusher. Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers horizontal shaft impactor and vertical shaft impactor.

Compressive strength of rocks PetroWiki

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.
