Which of the following is the main advantage of using laminated veneer lumber (LVL) over traditional timber?
- AHigher bending strength and stiffnessCorrect
- BGreater resistance to moisture
- CCheaper than solid timber
- DBetter aesthetic appeal
Solution
Concept
Laminated veneer lumber
Step-by-step solution
1. LVL is made of glued veneers with parallel grain. 2. It has higher strength and stiffness and less variability than sawn timber.
Explanation
The main advantage is higher bending strength and stiffness.
Why the other options are wrong
It is not cheaper, and moisture resistance and appearance are not its key advantage.
Shortcut
LVL = stronger, uniform.
Correct answer: A) Higher bending strength and stiffness
