If the depth of actual neutral axis of a doubly reinforced beam______________?
  • (A)  Is greater than the depth of critical neutral axis, the concrete attains its maximum stress earlier
  • (B)  Is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum stress earlier
  • (C)  Is equal to the depth of critical neutral axis; the concrete and steel attain their maximum stresses simultaneously
  • (D)  All the above
In a beam the local bond stress Sb, is equal to_______________?
  • (A)  Shear force/(Leaver arm × Total perimeter of reinforcement)
  • (B)  Total perimeter of reinforcement/(Leaver arm × Shear force)
  • (C)  Leaver arm/(Shear force × Total perimeter of reinforcement)
  • (D)  Leaver arm/(Bending moment × Total perimeter of reinforcement)
