Q: The flexural strength of an RCC beam depends on ________________.
  • A. the width of the beam only
  • B. neither the width nor the depth of the beam
  • C. the effective depth of the beam only
  • D. both width and effective depth of the beam
Correct Answer: Option D - The flexural strength of an RCC beam depends on both width and effective depth. The width influences the distribution of the load, while the effective depth determines the lever arm for resisting bending moments, making both factors crucial in determining the beam's strength against bending.
D. The flexural strength of an RCC beam depends on both width and effective depth. The width influences the distribution of the load, while the effective depth determines the lever arm for resisting bending moments, making both factors crucial in determining the beam's strength against bending.

Explanations:
