Question

The assumptions for the calculations for cables under distributed load are done for the cables. In that one of the assumption is that the cable is ___________

(a) Extensible

(b) Non-flexible

(c) Flexible

(d) Static

I have been asked this question in an internship interview.

My enquiry is from Cables Subjected to a Distributed Load topic in chapter Internal Forces of Engineering Mechanics

Answer 1

The correct answer is (c) Flexible

Easy 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.
