Question 1

What is the primary purpose of the specific gravity and density test in timber?

  • To find its cost
  • To measure weight-to-volume ratio
  • To test color

💡 Hint: Consider how understanding the 'weight' of wood helps in construction.

Question 2

True or False: Water displacement can be used to measure the volume of regular-shaped objects.

  • True
  • False

💡 Hint: Think about the shapes that would not fit into standard volume equations.

Challenge Problems

Push your limits with challenges.

Question 1

A certain type of softwood has a density of 600 kg/m³. If another hardwood has a density of 900 kg/m³, how much stronger is the hardwood expected to be based on density alone?

💡 Hint: Consider the ratio of their densities.

Question 2

A builder needs to choose between two wood types for a load-bearing beam. Type A weighs 800 grams with a volume of 600 cm³; Type B weighs 1200 grams with a volume of 900 cm³. Which type should the builder select and why?

💡 Hint: Calculate the density of each type and compare their values.
