@Kasi you are right.

Just check it once by opening the moment of inertia.

@Dhanya.

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

So it is wrong.
Pranjal said:   10 years ago
B can also be correct by substituting the value of I, please tell me.
Rahul said:   7 years ago
But depth effect will be more on deflection as (d^3).
So, it is C.
Kasi said:   9 years ago
Yes. All the given options are like correct answers. Check it once.
Abdullah said:   2 years ago
Both B and C are correct see the moment of inertia formula.

Azzu said:   7 years ago
As per my knowledge, the answer should be B and C.
Dalisha said:   9 years ago
Yes all answer are correct, you are right @Kasi.
AKV said:   7 years ago
A is correct.

Because weight will act as load.
Krishna said:   9 years ago
Why it is option C? Give the clear explanation.
