L/3+L/6 is L/2.

Multiply reaction with L/2 and subtract moment due to load ( load(W)*distance from load to center(L/6)).

Bending Moment at Center of the Beam = [W * (L/3 + L/6) ]-[W* (L/6) ]. How this come? Please tell me, I am not understanding.

Explain me briefly @Piyush Singh.

Ra-A........L/3...........!(w)..........2L/3...........B-Rb

Now moment at centre=[W*2L/3-W*L/3] = WL/3.
Now moment due to prestressing = P*h.
Now moment P*h should be > = for dip required.
P*h> = WL/3.
h> = WL/3P.
Generally h>or = WL/3P.
