For overhanging beam on both sides;

If a = length of overhang.
L= length of the overall span.
l = length of span b/w supports = L-2a;
(+ve) Max BM = (-ve) Max BM.
Wl^2/8 - Wa^2/2 = Wa^2/2.
a = l/2*2=0.35 * l.
a = 0.35(L-2a).
a = 0.207L.
Ratio; a/L = 0.207.

Max. BM = Min. BM.
If l= length of overhang.
L= length of ssb span.

wl2/8 - wl2/2 = wl2/2,
Solving this;
l/(L+2l) = 0.207.
