Question

The assumptions for the calculations are done for the cable subjected to its own weight. In that one of the assumption is that the cable is flexible and the other is that the cable is ___________

(a) Extensible

(b) Non-flexible

(c) Inextensible

(d) Static

The question was asked in an interview for internship.

I would like to ask this question from Cables Subjected to its Own Weight in section Internal Forces of Engineering Mechanics

Answer 1

Right option is (c) Inextensible

The explanation is: The assumptions are done so as to make the calculations easy. Though the assumptions make the small errors do not count over the big data. But still, if the assumptions are made then the calculations are easy. Thus the assumption taken as the cable is inextensible.
