7.2. Mechanical Tests

Try these first

1. 1.

   What does the compression test measure?

   Hint

   Think about how we use wood in construction.

2. 2.

   What does the Janka test indicate?

   Hint

   Consider what happens to wood floors or furniture over time.

3. 3.

   What is the primary purpose of mechanical tests on wood?

   • To evaluate aesthetic quality
   • To determine mechanical properties
   • To analyze chemical composition

   Hint

   Think about what makes wood safe to use in construction.

4. 4.

   True or False: The Janka test is specifically used to measure the moisture content of wood.

   • True
   • False

   Hint

   Consider what each test is meant to assess.

5. 5.

   You are given two types of wood: oak and pine. Describe how you would conduct a bending test on each and how you would expect their results to differ based on their known properties.

   Hint

   Consider the inherent densities and structural uses of each type of wood.

6. 6.

   Evaluate how understanding the shear strength of a wood beam can influence its design in a construction project, such as in a bridge.

   Hint

   Think about forces acting upon structures in real-life applications.
