Answer the steps.

Step 3: Calculation of main reinforcement (longitudinal or steel):
1. Design and detail a singly reinforced simply supported beam of Clear span
5.5 m to support a working live load of 60 KN/m. use Fe 460 steel and M30
grade concrete. Assume the support thickness as 220 mm. Over all depth
of the beam is given as D=570 mm.
