 If the beam is reinforced by 3- 25 mm bars, what is the safe moment capacity using transformed section method?

PROBLEM:
For the reinforced concrete beam shown, determine the area of the steel re-
inforcement for a balanced design. If so reinforced, determine the safe moment
capacity of the section, f'c = 20 MPa, fs = 140 MPa, n = 10
