The beam held to the level of end means deflection equals to zero @ med span.
Deflection from distributed load = 5wl^4/384EI (EQ: 1).
Deflection from PROP load = PL^3/48EI (EQ: 2).
From eq1 & eq2.
5wl^4/384EI = PL^3/48EI.
P = 5wl/8.
Deflection from distributed load = 5wl^4/384EI (EQ: 1).
Deflection from PROP load = PL^3/48EI (EQ: 2).
From eq1 & eq2.
5wl^4/384EI = PL^3/48EI.
P = 5wl/8.

No @Mukesh Kumar.
You are using deflection formula of a cantilever beam with UDL but here it is SSB.
