Sorry should have stated its inside! I understand the strength issue. My question was due to the fact that I've just got some figures back where the K2 factor has been incorporated for an Oak lintel over an internal door. The reason given on the calcs is that it's >100mm. The dims of the piece...
Charsat, Don't quite agree that birds don't have winglets. If you look at some birds of prey their wings definitely curve upwards at the ends during soaring - A kind of winglet I would suggest. Blended obviously!
Many Thanks AJUK. I am correct in thinking then that with C16 Timber this modification factor is not necessary? However, if the timber was Oak it would be prudent to apply this factor to allow for it being freshly sawn?
