Topic: Strength of Materials
In I-section shear load is resisted mainly by
- A. Flanges only
- B. Web only
- C. Both by flanges and web
- D. None
Answer: B. Web only
Explanation: In an I-section, the shear stress distribution is parabolic across the web and relatively small in the flanges. The maximum shear stress occurs at the neutral axis located in the web. Hence, the shear load is resisted mainly by the web.
