Q: The following two statements pertain to a simply supported under reinforced concrete beam. Select the correct option with regard to these statements. 1. The failure of the beam takes place due to the yielding of steel. 2. The moment of resistance of the beam is more than that of the balanced section of the beam.
  • A. Statement 1 is true but Statement 2 Is false
  • B. Statement 1 is false but Statement 2 is true
  • C. Both statements 1 and 2 are true
  • D. Both statements 1 and 2 are false
Correct Answer: Option A - Simply supported under reinforced concrete beam the failure of the beam takes place due to the yielding of steel. • Failure takes place by crushing of concrete after the steel has yield. • The neutral axis moves up as the load is increased
