A: To minimize the depression in a beam, it is designed as '' shape girder.
R: The '' shape girders have large load bearing surface, which decreases the stress
R: The '' shape girders have large load bearing surface, which decreases the stress
View answer and explanation
Correct option: A
If both A R are true and the R is the correct explanation of the A
Option A (If both A & R are true and the R is the correct explanation of the A) is correct because I-shaped girders are designed to minimize depression by having a large load-bearing surface, which reduces stress.
