Описание к видео T-Beam Design - What tensile steel area is required at midspan to resist a factored moment of...?

A floor system shown in the figure consists of a 75mm concrete slab supported by continuous T-Beams with a 7.5m span, 1.2m on centers. Web dimensions, as determined, are bw=275mm and d=500mm. What tensile steel area is required at midspan to resist a factored moment of 725kN-m if fy=420MPa and fc'=21MPa?
