A continuous cable (diameter 6 mm) with tension force T is attached to a horizontal frame member

Question:

A continuous cable (diameter 6 mm) with tension force T is attached to a horizontal frame member at B and C to support a sign structure. The cable passes over a small frictionless pulley at D. The wire is made of a copper alloy, and the stress stress-strain relationship for the wire is

(a) Find the axial normal strain in the cable and its elongation due to the load W = 6.8 kN.

(b) If the forces are removed, what is the permanent set of the cable?
