Looking through a second hand book sale over the weekend I came across a book published in 1912 called the Elementary Manual of Applied Mechanics.For those on the list who have contemplated making their own wooden rims I thought these figures for different woods might be of interest.The book cites them as Mean values in round numbers Elm 1,000,000 lbs per square inch Larch 1,100,000 Beech 1,300,000 Mahogany 1,400,000 Oak 1,500,000 Pine (yellow) 1,600,000 Ash 1,600,000 Teak 2,000,000
Geoff Duke who loves the idea but thinks it would be be all to scary in Melbourne Australia
