7.2.a. Compression Test (Parallel and Perpendicular to Grain)

Try these first

1. 1.

   What does the compression test measure?

   Hint

   Think about what happens to wood under weight.

2. 2.

   What are the two orientations for conducting a compression test?

   Hint

   Consider the direction of the wood fibers.

3. 3.

   What is the purpose of the compression test?

   • To measure weight
   • To assess load-bearing capacity
   • To evaluate aesthetic qualities

   Hint

   Think about what happens when weight is placed on wood.

4. 4.

   The compression test is performed in which orientations?

   • True
   • False

   Hint

   Consider how load could be applied in different ways.

5. 5.

   A beam made of pine wood is tested under compression parallel to the grain and shows a load-bearing capacity of 1500N. If another beam is tested perpendicular to the grain and shows a load capacity of 800N, what could this imply about the use of wood in different structural scenarios?

   Hint

   Consider how forces interact with the grain structure.

6. 6.

   Evaluate how varying moisture content in wood could alter the outcomes of compression tests conducted both parallel and perpendicular to grain. Suggest methods to mitigate these effects.

   Hint

   Think about how water changes a material's strength properties.
