In addition, a log (1.8-m length) was also collected from a section 0.2 to 2.0 m above the ground to examine the static bending properties of the lumber (95 by 45 mm in cross section).
Vibration and static bending tests were conducted on samples using three different methods of attaching sheathing to floor joists.
Four static bending specimens (76 by 242 mm), two TS specimens (152 by 152 mm), two linear expansion (LE) specimens (76 by 305 mm), and 12 IB specimens (50 by 50 mm) were cut from each panel and all properties were evaluated according to ASTM D1037-06a (ASTM International 2010).
In an evaluation of 15 eucalyptus clones that were between 5 and 6 years old, the modulus of elasticity obtained in the static bending of the specimens showed a coefficient of variation of 14 percent (Trugilho et al.
Clear static bending specimens were machined and tested.
In the case of DSB, the changes in chemical constituents as a function of retention time were not very significant because the mechanical properties of MDF (static bending, internal bond, and screw holding) produced from applying a higher digestion time do not fulfill the standard requirements of ANSI A208.2.
The static bending modulus of elasticity (MOE) of small clear wood specimens was about 15 and 20 percent greater than the dynamic MOE of green logs based on resonance vibration ([E.sub.fr]) and stress wave ([E.sub.sw]).
Red oak, sweetgum, and yellow-poplar specimens were treated in a 2-liter reactor at 150[degrees]C for 30 minutes, dried, and then weighed and tested by static bending. Three solutions, 1.0 percent sulfuric acid ([H.sub.2]S[O.sub.4]), water, and 1.0 percent sodium hydroxide (NaOH), along with untreated controls were used.
