Wire ropes are used very often not even in the area of civil engineering but in the all department of industry. The issue of cable structures and mechanical characteristics of wire ropes is paid close attention. The stress-strain diagram, which is not defined properly, does not determine the boundary between elastic and plastic area ambiguously. This paper is focused on the determination of mechanical characteristics of the single wire ropes under tensile load using the videoextensometry. The
