3.2. Mechanical Properties

Try these first

1. 1.

   Define compressive strength and give an example.

   Hint

   Think about the supporting role of beams.

2. 2.

   What is tensile strength?

   Hint

   Focus on forces that 'pull' apart.

3. 3.

   What type of strength is highest when timber is loaded along the grain?

   • Shear Strength
   • Compressive Strength
   • Tensile Strength

   Hint

   Think about the direction of weight support.

4. 4.

   True or False: Shear strength is greater than compressive strength.

   • True
   • False

   Hint

   Consider the directions of force.

5. 5.

   Design a small wooden bridge using timber. Discuss how you would select the type of wood based on its mechanical properties.

   Hint

   Compare strength properties of different timber types.

6. 6.

   Analyze a case where a wooden sports floor needs to resist shock loads. Determine the necessary hardness and toughness requirements.

   Hint

   Look for wood types used in gym flooring.
