8 Strength Of Soils And Rocks
In practical terms, the number itself isn’t all that meaningful, but it becomes useful to use in comparison with other woods. For instance, Ipe is known to have excellent strength properties among imported species, and has a crushing strength of 13,510 lb f in 2 (93.1 MPa). In comparison, White Oak is a well known wood used in cabinetry and furniture, and has a crushing strength of 7,440 lb.The strength of a rock mass will depend upon The number of cracks and joints The nature of their infilling material Whether there are any rock to rock contacts across the joints Planarity and continuity of seams and foliations Table Unconfined compressive strength of rocks.
