Figure 24-39. — Relationship of compaction ratio to modulus of rupture. Curved lines B 

 and C show 95 percent tolerance limits. Dashed lines indicate the compaction ratio 

 corresponding to an attainable minimum of 4,500 psi modulus of rupture. Data points 

 represent single-species panels of sweetgum, black tupelo, hickory, southern red oak, 

 post oak, white oak, sweetbay, white ash, and red maple veneer flakes. (Drawing 

 after Hse 1975c.)
