spruce wood in the Wright aircrafts
This is good what PBS is doing in teaching us about the Wright
brothers history. One almost wonders whether being bicycle mechanics was the prefered mechanical route to becoming the first builders of airplanes. I would hazard the guess that in the cosmos where and if intelligent life exists say 100 such exoplanets that all 100 built their first airplanes from the individuals who built bicycles or had bicycle training. And that all 100 exoplanets had to have bicycle technology in existence before they could build their first airplane. Further, I would speculate that all 100 such exoplanets when they built their first airplane such as the Wright's on Earth that all 100 were within 50 years of their first big war which we call WW1. In other words all 100 planets had to have a population large enough to build bicycles and to build their first airplane such that they were overpopulated and would soon have to engage in a World War on their planet to relieve their overpopulations. But I stray too far. Such is the trouble with a man who has so many theories that the minute I talk about one theory I soon am obliged to romp into other theories. I wanted to talk about spruce wood and how important it was in the Wright aircraft. Question: were the planes in WW1 made of wood? Was it spruce wood? Was the German ace of Red Baron a wooden plane? I love the superiority list of woods. Some say that hickory has the highest tensile strength and some say ash, as per baseball bats. I seem to think that ash beats hickory but am not set up to prove it. I did notice one means of testing in the growth of trees themselves. Because oak trees can throw a limb, a big limb at that to nearly parallel the ground so the wood has to be extraordinarily tough to hold a massive limb parallel to the ground. So oak must be strong and tough. But Hickory or Ash seem not able to parallel the ground indicating to me that oak is superior in strength than Hickory or Ash. Perhaps not tensile-strength but some sort of other strength. I suppose if Oak were lighther than Spruce that the Wright Brothers would have prefered oak. I know that spruce has a dense foliage and so its root and wood system must be special in order to stand upright in those Colorado wind gales. So the Spruce wood must be strong to withstand the wind but must be light because it is a soft wood. And the canopy needle cover of spruce is so dense that you cannot see through it so the wood must be strong to hold the tree upright and stronger than pines. I believe the science of botany should appoint a team of experts on wood with the collobaration of physicists and engineers to make a encyclopedic analysis of all the world's woods as to their superlatives and characteristics. Their density, their strengths and many other characteristics. So much of wood knowledge is folklore and myths and not really the full truths. So we need experts to go into this and to reveal the best science on "Wood Characteristics".

Didja hear the the superior sound qualities of the violins of Stradivarius et. al. has been attributed to the mini-Ice Age? The trees of the era had much narrower growth rings than those of modern trees, making their wood stiffer. That's why it's impossible to make a forgery using wood from trees of this warm period that sounds "right". Now all you have to do is extrapolate what kinds of wood-analogues can grow in planetary chemistries subtly or wildly different from ours, AND take into acount climatic variations on said planets. Good luck. Mark L. Fergerson |

I suspect all of the references in the present literature were never really conducted as per a "full fledged scientific analysis" and that the numbers achieved in all books on wood to date are mostly numbers got from less than a scientific laboratory would get.

Trouble with too much of the old literature on wood with number data is that the testing was not done under Science Rigor. + + + How much of this "old literature" did you see? + + + To get a hickory to beat out oak and ash is as simple as finding a hickory with narrow tree rings to compare with oak and ash of wide tree rings. + + + The other way about.

I feel that the strength of oak exceeds that of hickory or ash just from the ability of oak limbs to parallel gravity. -------- Talking aircraft ....... weight, weight, weight!

Thanks for the references. I suspect all of the references in the
present literature were never really conducted as per a "full fledged scientific analysis" and that the numbers achieved in all books on wood to date are mostly numbers got from less than a scientific laboratory would get. Then see: USDA Handbook #72 "Wood Handbook Wood as an Engineering Material". Your tax dollars at work. The true hickories are by far the "stronger" materials no matter which mechanical property one is considering. |
