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.
