Question

In a girder of rectangular cross-section, the longer side is used as

(A) length

(B) breadth

(C) depth

(D) all of above​

Answer 1

Answer:

the answer is depth hope it's help

Answer 2

Answer:

In a girder of rectangular cross-section, the longer side is used as depth.

Therefore, the correct option is (C) depth

For a given load,

depression (δ)

δ ∝ 1/b

δ ∝ 1/d³

δ = Wl³/4bd³Y

So, depression becomes smaller when the depth is made larger.

Therefore, to make the value of depression small, the longer side in a girder of rectangular cross-section is used as depth.
