Question

Square or rectangular sawn timber under 15 cm in section is calld as _______

• A. Beams
• B. Scantlings
• C. Blocks
• D. Planks

Hint:

Remember the cutoff limit:
- Under \(15\ \text{cm}\) cross-section \(\rightarrow\) Scantling
- Equal to or greater than \(15\ \text{cm}\) cross-section \(\rightarrow\) Beam

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Sawn timber is classified into distinct commercial categories based on its cross-sectional dimensions and shapes to standardize its trade and structural utilization.

Step 2: Detailed Explanation:
Let us review the standard Indian commercial definitions for sawn timber:
1. Scantling: Sawn timber that has a square or rectangular cross-section where the width and thickness are both under \(15\ \text{cm}\).
2. Beam: A large, heavy structural timber where the cross-sectional dimensions exceed \(15\ \text{cm}\) in width and thickness.
3. Plank: A long, flat piece of timber where the width exceeds \(15\ \text{cm}\) and the thickness is typically under \(5\ \text{cm}\).
Therefore, square or rectangular sawn timber under \(15\ \text{cm}\) in section is commercially referred to as a scantling.

Step 3: Final Answer:
The commercial term for sawn timber under \(15\ \text{cm}\) in cross-section is Scantlings.
