Yes, all the above are correct.

Good explanation @Bikash Kabiraj.

Keshav said:   8 years ago
It is also inversely proportional to width.

Pradipto Sarkar said:   8 years ago
As per my knowledge, the answer will be (E)... because;

(a) not directly proportional to its weight but the load.
(b) I may be 1/12 db^3.
(c) same as (b).
(d) power of l changes with the load.

Abhi said:   8 years ago
All answer are correct.

Abdul sovan khan said:   8 years ago
I think 'E' option should be 'ALL OF THESE'.

Azzu said:   7 years ago
As per my knowledge, the answer should be B and C.

AKV said:   7 years ago
A is correct.

Because weight will act as load.

Rahul said:   7 years ago
But depth effect will be more on deflection as (d^3).
So, it is C.

RAKESH said:   7 years ago
Only I=BD*3/12 will remain same in all condition of deflection. So, C option must be right.
