Question:
_________ is a build up board having a core of light material, faced on both sides with a relatively thin layer of material having high strength properties.
_________ is a build up board having a core of light material, faced on both sides with a relatively thin layer of material having high strength properties.
Show Hint
Think of the food alogy: a "sandwich" has two outer layers of bread (stiff, high-strength faces) holding together a soft inner filling (lightweight core).
This design minimizes material weight while maximizing bending resistance.
This design minimizes material weight while maximizing bending resistance.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Engineered wood products are composite materials designed to optimize the strength-to-weight ratio for specific structural and packaging applications.
Step 2: Detailed Explation:
A sandwich board (or sandwich panel) is a three-layered composite structure.
It is constructed by attaching two thin, stiff, and high-strength face sheets (often made of plywood, fiber sheets, or metal) to both sides of a thick, lightweight core material.
The core material (such as balsa wood, structural foam, or honeycomb plastics) keeps the outer skins apart, providing high bending stiffness and strength with minimal weight.
This structural configuration behaves similarly to an I-beam, where the face sheets resist tensile and compressive bending stresses, while the lightweight core resists shear stresses.
Plywood is made of thin wood veneers glued together with alterting grain directions; lamited wood consists of parallel timber lamitions; and fiberboard is made from compressed wood fibers.
Step 3: Fil Answer
The described structural engineered composite board is a sandwich board.

- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
