Plywood has the advantage of A. Greater tensile strength in longer direction B. Greater tensile strength in shorter direction C. Same tensile strength in all directions D. None of the above

The correct answer is: A. Greater tensile strength in longer direction.

Plywood is a type of wood that is made by gluing together thin sheets of wood. The sheets are usually arranged in a cross-grain pattern, which gives plywood its strength. Plywood is stronger in the direction of the long grain than in the direction of the short grain. This is because the long grain fibers are aligned in the same direction, which makes them more resistant to breaking.

Option B is incorrect because plywood is not stronger in the shorter direction. Option C is incorrect because plywood does not have the same tensile strength in all directions. Option D is incorrect because plywood does have the advantage of greater tensile strength in the longer direction.
