Crushing (gripping) strength. This type of strength is often developed with "traditional" wrist and forearm exercises, such as squeezing a rubber ball, compressing a hand gripper and/or working on wrist rollers. With this type of strength, the palm remains stationary while the fingers move toward it in a gripping movement.

Crushing is the magical ability to create force around an object or power, squashing and neutralizing it as a result. Crushing is achieved through sheer magical power or accessed through powers such as telekinesis and super strength. A prime example of this ability is being used is whenever beings catch an energy ball with their bare fist and crush it. Another notable occurrence is when Chris ...

compressive strength—a measure of the ability of the concrete to withstand crushing loads. elastic limit—the limit to which a material can be stressed (stretched or shortened axially) and still return to its original length when unloaded. Loads below the elastic limit result in the material being deformed in proportion to the load.

high-strength cable can break at only 21,500 lbf. The safe working load of the standard high-strength cable is 14,000 lbf, 4,000 lbf less than that of TuffLINE 18000 cable. For conventional cable, crushing cold flow of the core occurs at about 10,000 lbf, whereas TuffLINE 18000 cable can spool up to 16,000 lbf without crushing or requiring
