TABLET BREAKING FORCE

The breaking force of tablets is commonly called hardness in the pharmaceutical literature; however, the use of this term is misleading. In material science, the term hardness refers to the resistance of a surface to penetration or indentation by a small probe. The term crushing strength is also frequently used to describe the resistance of tablets to the application of a compressive load.

Compressive strength - Wikipedia

When a specimen of material is loaded in such a way that it extends it is said to be in tension. On the other hand, if the material compresses and shortens it is said to be in compression. On an atomic level, the molecules or atoms are forced apart when in tension whereas in compression they are forced together. Since atoms in solids always try to find an equilibrium position, and distance between other atoms, forces arise throughout the entire material which oppose both tension or compression. The phenomena prevailing on an atomic level are therefore similar.

Big Forearms, Crushing Grip T NATION

Aug 28, 2013  Bodybuilders are often only concerned with forearm size, which requires an entirely different approach from grip strength. For a stronger grip, choose passive crushing, active crushing, pinch gripping, and thick bar work. For bigger forearms, choose wrist curling, static holds, and extensor work, all with moderate loads for higher reps.
