Consider a 2-D object consisting of two triangle compartments, as shown in Figure P9.4. Suppose a solution containing a 511 KeV gamma ray emitting radionuclide with concentration f = 0.5….
Explain how heartwood is different from sapwood.
2. Explain how heartwood is different from sapwood. Understanding this difference, how deep would you need to drill a hole in an 18-inch diameter maple tree to get sap for making syrup?
3. A piece of oven-dried wood weighs 3.7 pounds and has a total volume of 113.8 inches3. The specific gravity of the wood solids only is 1.5 (if you could compact the dry wood into a solid mass). The volumetric shrinkage of the wood, from green to oven-dried state, was 14.5 percent.
a. What is the oven-dried specific gravity that should be reported?
b. What should be the reported unit weight of the wood, in pounds/feet3?
c. What is the maximum moisture content of the green wood (if all wood voids were filled with water)?
