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.

Basic characteristics. Narrow aisle racking systems are a major alternative to multi-bay racking systems. They offer all the performance features of multi-bay racking at heights above 10 m and are freestanding in the warehouse. They are characterised by the small amount of floor space required for aisles and the extremely large lift heights. Narrow aisle racking is used in particular when a) there is only limited space available and b) there is a necessity for greater throughput in comparison with multi-bay racking systems.
