Question No 102 option D should be correct (Question:1037732.0)

As deflection is inversely proportional to the EI. That's why we take the larger side as depth. So we can decrease deflection and increase the strength of the beam section.

Question:

Two cantilever steel beams of identical length and of rectangular section are subjected to same point load at their free end. In one beam, the longer side of section is vertical, while in the other, it is horizontal. Beams defect at free end:

Options:
A)

equally irrespective of their disposition.

B)

more in case of longer side vertical.

C)

less in case of longer side horizontal.

D)

less in case of longer side vertical.

Solution:

Ans: (a)

Dear Student,
The deflection of the cantilever beam depends on the length of the beam and load applied at the free end.
So deflection will be the same for same load and same length. Here EI is constant.
The given answer is correct.
