1. The advantage of reinforced concrete, is due to
2. In a singly reinforced beam
3. In a singly reinforced beam, the effective depth is measured from its compression edge to
4. If the modular ratio is m, steel ratio is r and overall depth of a beam is d, the depth of the critical neutral axis of the beam, is
5. The section of a reinforced beam where most distant concrete fibre in compression and tension in steel attains permissible stressess simultaneously, is called
6. If the permissible compressive and tensile stresses in a singly reinforced beam are 50 kg/cni2 and 1400 kg/cm2 respectively and the modular ratio is 18, the percentage area At of the steel required for an economic section, is
7. In a singly reinforced beam, if the permissible stress in concrete reaches earlier than that in steel, the beam section is called
