Consider the following statements regarding the working stress design of under reinforced RC section:
1. The neutral axis depth will be greater than that of a balanced section
2. The stress in steel in tension will reach its maximum permissible value first
3. The moment of resistance will be less than that of the balanced section
4. The concrete on the tension side is also considered for calculating the moment of resistance
