Adamantium: Crushing Strength. Crushing strength is one of the four pillars of grip strength, and is the act of closing the fingers into a fist against a resisting force. This makes it a true concentric movement, which means that this type of strength is characterized in moving against the resisting force.

Collapse pressure (or PVC pipe crush strength) is the amount of outside pressure a pipe can take before it starts collapsing inwards. This is an important measurement when burying pipe for subterranean appliions. To test this type of strength, you can place weight on a pipe until it starts buckling.

Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of ''setting'' and ''hardening'' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be ''set'' in that it is no longer fluid, but it may
