Transcribed Image Text:A reinforced concrete beam has a width of 400mm and a total depth of 550mm. The longitudinal bars at the top are 2 - 28mm
and 4-32mm at the bottom. Concrete strength is f' c = 22MPa (pc=1950kg/m3) and steel yield strength fy = 420MPa. Steel
cover is 70mm. Compute for the modular ratio.
