NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a beam that is supported at the ends and loaded at the center. Three different cross-sectional shapes of the beam are observed: (a) rectangular section of a bar, (b) a thin bar that can buckle, and (c) a commonly used section for a load-bearing bar. Which cross-sectional shape is most effective in providing a large load-bearing surface and enough depth to prevent bending?
A
Rectangular section of a bar
B
Thin bar that can buckle
C
Commonly used section for a load-bearing bar
D
None of the above
Correct Answer
Option C
Detailed Explanation
The commonly used section for a load-bearing bar is designed to provide a large load-bearing surface and enough depth to prevent bending, thus reducing weight without sacrificing strength.
