Q. If the depth of actual neutral axis of a doubly reinforced beam (Solved)
1. Is greaterthan the depth of critical neutral axis, the concrete attainsits maximum stress earlier
2. Islessthan the depth of critical neutral axis, the steel in the tensile zone attainsits maximum stress earlier
3. Is equal to the depth of critical neutral axis; the concrete and steel attain their maximum stresses simultaneously
4. All the above
- d. All the above
