When testing the timber specimen in compression parallel to the grain, a
significant deviation from the procedures prescribed in ASTM D 143, "Standard
Test Methods for Small Clear Specimens of Timber," was: - correct-answer-Not
using a displacement-controlled loading scheme (e.g., inch/minute)
The clear-grade Douglas fir timber specimen tested in the CE 200L laboratory in
shear parallel to the grain would have been stronger if : - correct-answer-Instead,
it had been tested perpendicular to the grain
Water Content = - correct-answer-Water mass Wet / Water mass Dry
Lime increases - correct-answer-Workability, Bondage Strength of Mortar and
keeps water inside the mix
Timber has high - correct-answer-Strength / Weight Ratio
