Impact of Knots on the Strength of Wood
The strength of wood beams and columns is an important parameter that governs the design of structures. In this video, we investigate how strong wood actually is and why we use lower values during design. As one of the main and most important construction materials, understanding wood is absolutely crucial. The video also touches on and explains size-effects as an important design consideration. Furthermore, a statistical explanation is provided for the strength value used in design manuals around the world.

Wood is Strong, can be finished attractively with it's grain exposed and polished. most of all it doesn't need RE-BAR to strengthen it. Concrete is useful but ugly, deteriorate quicker than wood if not tended to. All the figures are great but being from an Engineering background myself a lot of it is simply known by your intelligence. I mean you don't build a bridge out of Block board! lol! or a bridge out of neat concrete without re-bar strengthening?
