Consider a beam supported at the ends and loaded at the centre as described in Fig. 8.6, with different cross-sectional shapes shown in Fig. 8.7. Which cross-sectional shape is commonly used for load-bearing applications due to its structural efficiency?
A
Rectangular section of a bar
B
A thin bar
C
A shape providing a large load-bearing surface with depth to prevent bending
D
A pillar with rounded ends
Correct Answer
Option C
Detailed Explanation
The commonly used section for load-bearing applications is the one that provides a large load-bearing surface and depth to prevent bending, as it reduces weight without sacrificing strength.
