The strength of plywood in the direction of the grain is compared to the strength across the grain in which way?
- AStronger along the grainCorrect
- BStronger across the grain
- CEqual in both directions
- DPlywood has no directional strength
Solution
Concept
Directional strength of plywood
Step-by-step solution
1. The face veneers run along the length. 2. Plywood is stronger along the face grain.
Explanation
Alternate layers are at right angles, but the surface veneers are along the grain, so plywood is stronger in that direction.
Why the other options are wrong
It has directional strength.
Shortcut
Stronger along the face grain.
Correct answer: A) Stronger along the grain
