Can anybody clearly explain it?

B & C both are correct.

I = bd^3 /12.

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.

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.
