Episode 109 What Do Those Wood Technical Numbers Mean

Shannon's Lumber Industry Update · 109 – Applied Wood Technical Properties

Applied Lumber Technical Properties

This is kind of a review of episode 5 but ideally a bit more applied look at what all those number mean when it comes to actually working with wood.  In this episode I look at what I find are the most important numbers to consider and the tests that give us these numbers.  Just remember wood is orthotropic which means its strength properties are not the same in all directions.  Its is also anisometric (or anisotropic) which means it moves differently in all directions.  That second term is just to impress people at dinner parties.

Hardness (check out episode 29 on Janka Hardness)Density/Specific GravityWeightMOR/MOE (check out episode 35 on MOR/MOE)T/R ratioShearing Strength (check out episode 30 on Shearing Strength)Crushing Strength 

More information on these properties, what they mean, and the tests performed to get the actual data can be obtained in the Wood Handbook published by the Forest Products Laboratory.  Download your copy today for outstanding bedtime reading!  You will find that many other countries have developed a similar "handbook" with a bit of creative Googling.
