Woodworking Wood Types And Properties 1 — Questions and Answers
Question 1: Which type of wood is classified as a hardwood?
- Oak (Correct answer)
- Pine
- Cedar
- Spruce
Correct answer: Oak
Oak is a hardwood because it comes from a deciduous (broad-leaved) tree, unlike softwoods such as pine, cedar, and spruce which come from conifers.
Question 2: What does the term 'grain' refer to in woodworking?
- The pattern of wood fibers (Correct answer)
- The weight of the lumber
- The moisture content
- The color of the wood
Correct answer: The pattern of wood fibers
Grain refers to the alignment, texture, and pattern of the wood fibers as they grow within the tree.
Question 3: Which wood species is known for its natural resistance to rot and insects?
- Cedar (Correct answer)
- Poplar
- Birch
- Maple
Correct answer: Cedar
Cedar contains natural oils that make it highly resistant to rot, decay, and insect damage, making it ideal for outdoor projects.
Question 4: What is 'end grain' in a piece of wood?
- The cross-section exposed when a board is cut perpendicular to the growth rings (Correct answer)
- The outer bark of the tree
- The grain visible on the face of a board
- The grain on the narrowest edge of a board
Correct answer: The cross-section exposed when a board is cut perpendicular to the growth rings
End grain is the surface revealed when wood is cut perpendicular to the direction of the wood fibers, exposing the annual rings.
Question 5: Which of the following is a characteristic of softwood compared to hardwood?
- Generally faster growth and lower density (Correct answer)
- Harder and more durable surface
- Always darker in color
- Only grows in tropical regions
Correct answer: Generally faster growth and lower density
Softwoods typically grow faster and have lower density than hardwoods, which is why they are generally less expensive and easier to work with.
Question 6: What is 'figure' in woodworking terminology?
- Distinctive visual patterns in wood caused by grain variations (Correct answer)
- The thickness of a board
- The number of annual rings per inch
- The moisture content percentage
Correct answer: Distinctive visual patterns in wood caused by grain variations
Figure refers to distinctive visual patterns—such as curly, quilted, or burl patterns—created by irregular grain growth in wood.
