why is crushing strengh is required

In practical terms the number itself isnt 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 13510 lb f in 2 931 MPa In comparison White Oak is a wellknown wood used in cabinetry and furniture and has a crushing strength of 7440 lb
