7.1. Physical Tests

Try these first

1. 1.

   What is the formula for calculating moisture content in wood?

   Hint

   Consider how you calculate differences in weights.

2. 2.

   What does density indicate about wood?

   Hint

   Recall how heavy wood feels relative to its size.

3. 3.

   What method is used to test moisture content in wood?

   • Kinetic method
   • Oven-drying method
   • Chemical method

   Hint

   Recall the process involving drying the wood sample.

4. 4.

   True or False: Higher density wood is always weaker than lower density wood.

   • True
   • False

   Hint

   Think about how weight correlates to strength.

5. 5.

   A wood workshop found that their lumber's average moisture content was 25%. If they want to reduce it to 12%, what percentage of moisture must they remove?

   Hint

   Simple subtraction will lead you to the answer.

6. 6.

   You have two types of wood: Wood A with density 0.85 g/cm^3 and Wood B with density 1.20 g/cm^3. If you need to select a wood for structural support, which would you choose and why?

   Hint

   Think about which wood type can withstand more weight.
