Which cross-section of the beam subjected to bending moment is more economical?
Show Hint
- Rectangular cross-section
- I - cross-section
- Circular cross-section
- Triangular cross-section
The Correct Option is B
Solution and Explanation
Step 1: Understanding economical beam cross-sections.
- The I-section provides maximum strength with minimum material.
- This reduces material cost while ensuring high bending resistance.
Step 2: Selecting the correct option. Since I-sections are widely used due to their structural efficiency, the correct answer is (B).
