I working stress Method Permissible bending Tensile stress = fck/factor of safety = 25/14.

You are right, thanks @Sheela.

Isn't it 0.7√fck?

Shantanu said:   6 years ago
The formula is 0.25 √of grade of concrete.

Monika said:   7 years ago
According to me, it is 1.7 √fck.

@Hariram.

As per IS Code: Permissible bending stress= 0.36*√ fck= 0.36*√ 25= 0.36*5 = 1.8.
