Calculation of neutral axis and type of section. The singly reinforced cross section is checked for under reinforced or over reinforced.

x_u/d :

The section is :

---

The moment of resistance is : N-mm.

or

The moment of resistance is : kN-m.

---

Calculation of safe load :

Factored load is : kN/m.

Safe working load is : kN/m.

Dead load : kN/m.

Live load : kN/m.
