It should be wl^2/3EI for DEFLECTION.

Where as Wl^2/2EI for the SLOPE.

Bhaskar said:   5 years ago
Deflection = ML^2/3EL.
Max Deflection = 1.5 deflection.
=1.5 * ML^2/3EI,
=ML^2/2EI.

BMD is rectangular due to this deflection is,
ML^2/EI(1/2)= ML^2/2EI.

Kirana said:   6 years ago
Yes it should be ML^2/3EI.

Ruchir Singh said:   7 years ago
Given answer is correct.

This is the standard value result.
Value of slope = ML/EI.
Value of Deflection= ML^2/2EI.

It should be ML^2/3EI.

I think it should be Option (A) ML^2/3EI.
As we know that,
Deflection in a Cantilever due to Load P at its free end is,
PL^3/3EI
Since, M=P.L
So,

(P.L)L^2/3EI
(M)L^2/3EI
So,

Deflection=ML^2/3EI (Option A).

Go through double integration method you would get the answer.
