I$\text{'}$d like some help with obtaining the maximum load this beam can carry $($predicted failure load$)$ of this singly reinforced concrete beam. Thanks.

We are given fck$=25$N$/$mm$^2$ and fyk $=500$N$/$mm$^2$

The diameter of the tension bars are $10$mm

Breadth of the beam $=150$mm

Effective depth $=140$mm

Length of beam $=1200$mm
