In which case, the bending stress will be negative?

Please explain.

In bending stress equation, why it is Ix in both the direction?

I think it should be Ix for Mx and Iy for My. If this statement is correct, then equation will be Combined stress =(P/A) + (Mx/Ix) + (My/Iy). Is this right? Please tell me.

Thanks @Ranguwal.

Thanks @Ranguwal.

In the denominator, it always to occur in a square within the bracket value because the load is in N or KN so, p/bd outside has the unit N/mm2 & in the bracket, mm2 should be needed so ONLY FIRST option gives the same units so think wisely>>::.

Iy= db3 /12. So, in answer b2 should be for P * ey * y/ b2.

Thanks @Roshan.

Normal stress = p/A.
Bending stress= Mx*y/Ix + My*x/Ix.

Adding both, P/A +M*Y/I .
where A=(b*d) and Mx= P*ey, My= P*ex, Ix= bd3/12; Iy=db3/12.
