Q375

Plywood is made from

A.
Common timber
Answer
B.
Bamboo fibre
C.
Teak wood only
D.
Asbestos sheets

Answer: Option A

Solution

Answer: Option A
Solution:
Plywood is made from common timber. It is a type of engineered wood product manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. This cross-graining technique enhances the strength and stability of the plywood, making it suitable for various applications in construction, furniture-making, and other industries.

Bamboo fibre is not typically used in the production of plywood. While bamboo can be processed into various building materials, including bamboo plywood, it is not the primary material for traditional plywood production.

Teak wood is a valuable hardwood known for its durability and water resistance, but plywood is not exclusively made from teak wood. Common timber species such as pine, cedar, and spruce are more commonly used in plywood production.

Asbestos sheets are not used in the manufacture of plywood. Asbestos is a hazardous material and has been largely phased out of construction materials due to health concerns.

Therefore, Option A: Common timber is the correct material from which plywood is made.
