44.
A simply supported beam , 6 m long and of effective depth 50 cm, carries a uniformly distributed load 2400 kg/m including its self weight. If the lever arm factor is 0.85 and permissible tensile stress of steel is 1400 kg/cm2, the area of steel required, is

I think it is 18 cm^2.

It's permissible tensile stress we would not multiply 0.85.

Ast = M/0.85(tensile stress * lever arm * depth).
M = wl^2/8,
Ast = 15.725.
M = wl^2/8,
Ast = 15.725.
