10.9 A wood pole with a diameter of 10 in. has a moisture content of 5%. The fiber saturation point (FSP) for this wood is 30%. The wood shrinks or swells 1% (relative to the green dimensions) in the radial direction for every 5% change in moisture content below FSP. a. What would be the percent change in the wood's diameter if the wood's moisture is increased to 55%? b. Would the wood swell or shrink? c. What would be the new diameter?

Transcribed Image Text:10.9 A wood pole with a diameter of 10 in. has a moisture content of 5%.
The fiber saturation point (FSP) for this wood is 30%. The wood shrinks or
swells 1% (relative to the green dimensions) in the radial direction for every
5% change in moisture content below FSP.
a. What would be the percent change in the wood's diameter if the
wood's moisture is increased to 55%?
b. Would the wood swell or shrink?
c. What would be the new diameter?
Expert Solution
Step 1
Given,
Diameter of wooden pole = 10 in
Moisture content = 5%
Fiber saturation point, FSP = 30%
