A doubly reinforced concrete beam is 25 cm wide and 50cm
deep to the centre of tension reinforcement. The centre of
compression is steel is 5cm from the compression edge. The
areas of the compression and the tension steel are 10.16cm2
and 12.56 cm2 if m=18 and the bending moment at the section
is 7,000,000 N-cm. Calculate the stress in concrete and
steel.
