What Is Potassium? Potassium is a mineral that, among other things, helps muscles contract, helps regulate fluids and mineral balance in and out of body cells, and helps maintain normal blood pressure by blunting the effect of sodium. Potassium also may reduce the risk of recurrent kidney stones and bone loss as we age.
Racking strength, simply explained, is the ability of a square or rectangular (wall) area to maintain its shape under duress. The picture below (from an old federal document testing racking strength) demonstrates what can happens with stress exceeds a wall's racking strength.acking strength, simply explained, is the ability of a square or rectangular (wall) area to maintain its shape under duress.

10. Clearly the gluing method provided superior racking stiffness and racking strength with a 40-50% increase in racking strength and about a 50% increase in racking stiffness for paperboard A. The average values of buckling extents and initial slopes (average-type) are compared for the two methods in Table 3.EER-REVIEWED ARTICLE ncsu.edu/ bioresources Bi and Coffin (2006). âRacking Strength of Paperboard,â B io R esources 2(1), 3-19. 9 portion of the curve corresponds to lifting the frame off the bottom support.
