4.15 (B). A rectangular reinforced concrete beam is 200 mm wide and 350 mm deep to reinforcement, the latter
consisting of three 20 mm diameter steel rods. If the following stresses are not to be exceeded, calculate: (a) the
maximum bending moment which can be sustained, and (b) the steel stress and the maximum concrete stress when
the section is subjected to this maximum moment.
Maximum stress in concrete in bending not to exceed 8 MN/m.
Maximum steel stress not to exceed 150 MN/m?.
Modular ratiom- 15.
[1.Struct. E.) [38.5 kN m; 138, 8 MN/m']
