Concrete Technology and Design of Concrete Structures
If the depth of neutral axis for a singly reinforced rectangular section is represented by kd in working stress design, then the value of k for balanced section

depends on aCbC only

depends on as, only

depends on both crst and acbc

is independant of both ast and acbc where d is the effective depth, ast is per-missible stress in steel in tension and ocbc is permissible stress in concrete in bending compression.
