A doubly reinforced concrete beam has effective cover 'd' to the centre of compression reinforcement. 'xu' is the depth of neutral axis, and 'd' is the effective depth to the centre of tension reinforcement. What is the maximum strain in concrete at the level of compression reinforcement?
Consider the following statement:
In an underreinforced concrete beam,

2. concrete reaches ultimate stress prior to steel reaching the ultimate stress.
3. moment of resistance is less than that of balanced sections.
4. lever arm of resisting couple is less than of balanced sections.
Which of those statements is/are correct?
