Deflection from distributed load = 5wl^4/384EI.
Deflection from PROP load = PL^3/48EI.
5wl^4/384EI = PL^3/48EI.
P = 5wl/8.
Deflection from PROP load = PL^3/48EI.
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.

Ans is 3wl/8.
As at simply supported beam deflection is zero.
Deflection due to distributed load w is wl^4/8EI,
Deflection due to support reaction is pl^3/3EI,
Both are equal so p=3wl/8.

A beam of span l is fixed at one end & simply supported at other end. It carries uniformly distributed load of w per unit run over the whole span. The reaction at the simply supported end is what ?
