Question

Being inextensible the cables under distributed load has ___________ length.

(a) Infinite

(b) Zero

(c) Average to zero

(d) Constant

The question was posed to me in an interview for job.

Question is from Cables Subjected to a Distributed Load in portion Internal Forces of Engineering Mechanics

Answer 1

Right choice is (d) Constant

Explanation: The assumption that the cables are inextensible the main fact that comes out is that the cable length is constant throughout. Thus in the calculations also the fact that the length is constant makes a huge time saving tool. Thus the length of the cables are to be assumed constant if the assumption is taken as they are inextensible.
