Mechanical Properties of Wood

Excerpt from The Mechanical Properties of Wood One of the principal objectives of laboratory investigations is to determine values per unit area for the various strength proper ties of wood. These, however, because of the complex structure of wood, cannot have a constant value that will be exactly repeated in each test, even though no error be made. The most that can be accomplished is to find average values, the amount of variation above and below this average, and the laws that govern the variation.
