In working stress design, if the neutral axis depth for a singly reinforced rectangular beam is denoted by kd, what does the value of k represent for a balanced section?

Explanation

The value of k for a balanced section is governed exclusively by the allowable tensile stress in steel (ast). It does not depend on the permissible compressive stress in concrete (acbc). Here, d is the effective depth, ast is the permissible tensile stress in steel, and acbc is the permissible compressive stress in concrete under bending.
