just weight

[innaminnit]

Est. lbs. per sq. in. of Northern red oak (green) trying to figure by area the weight of sections 36 " diam. by 32" length. They were hittin' the ground with a kind of dull thud after walking them off the butt with a pry bar - closest I could est. is maybe 1000 lbs. Any mathmaticians out there?

I get 939.645 lbs. Been awhile since i have done weight calculations. Area = 3.14 x radius squared. (3.14 x 18 squared) A= 1017.36. Thats square inches we want feet so divided by 144 = 7.065 square feet. Times that by height. 7.065 x 2.66 = 18.7929. Times that by 50 = 939.645 lbs. Clear as mud?

 

[no tree to big]

or use the chart posted previously go to 36" red oak which is 445# a foot times that by 2.66 and that gives you 1183.7# per piece

not sure where 50# came from should be 63...

50 was on the weight chart I looked at. I see sherrill has it as 63.

Sir,

Good math.

Now what about all those limbs?

My chart shows 63# per cubic ft for Red Oak also.

well that was not part of the question so i need further info how big are the limbs? how much taper how much foliage?

 

[Youngbuck20]

I was looking at another chart on google and it had "northern red oak" it was 50. I'll look for it again. I was told that foliage makes up for 20% of the weight. Of course that can't be true with every tree but I guess that's average. As for limbs, diameter and length needed.
