solution:

Fy=0
Ry=0


Ma=0 M=Mo Image(189).jpg

EI(d^2V/dX^2)=Mo

EI(dV/dX)=Mo+C1
EIV=(Mo^2*X^2/2)+C1X+C2

AT X=0 V=0 C2=0
AT X=0 (dV/dX)=0 C1=0

EI(dV/dX)=MoX slop= (dV/dX)=(MoX/EI)

EIV=MoX^2/2 the equation of the elastic curve= (MoX^2/2EI)


AT X=L the deflection at the end=V=MOL^2/2EI
the solp at the end=(MoL/EI)
