All of these correct.

PRAVEEN SHARMA said:   9 years ago
In case of loading deflection is wl3/48 EI. So, Deflection is directly proportional to the weight of beam.

Dhanya S said:   9 years ago
It is also directly proportional to the cube of it's length. So option D can also be correct.

@Kasi you are right.

Just check it once by opening the moment of inertia.

Dalisha said:   9 years ago
Yes all answer are correct, you are right @Kasi.

Sanjeev ranjan said:   9 years ago
All answers are correct, all of the above is a better option at the place of none of these.

@Dhanya.

In case of udl then, deflection = 5wl^4/384EI.

So it is wrong.

Jwala said:   9 years ago
Yes, option b and c are correct.

Pavan said:   8 years ago
According to me, the answer should be all the above read it carefully you will understand.

W is applied force.
Deflec=wl^3/48ei,
i=moment of inertia,
i=bd^3/12 so option c is correct.
