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 ___________

(a) Extensible

(b) Non-flexible

(c) Flexible

(d) Static

This question was addressed to me during a job interview.

Enquiry is from Cables Subjected to its Own Weight topic in division Internal Forces of Engineering Mechanics

Answer 1

The correct choice is (c) Flexible

Best explanation: 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 perfectly flexible.
