The tensile test result shows that the strength of the rope was only 45 % of the bulk strength. Since the rope was formed by twisting two strands, which are twisted by themselves oppositely, it is considered to be due to structural degradation, for example, the outer parts are required more stretch than inner parts. Specimen ropes of various twist angle of strands without changing the twist angle of strands themselves were tested to find the influence of the twist angle on the break strength of the rope. Test result shows a slight degradation as the twisted angle becomes larger. Tensile strength of ropes including cross section of various cross angles were also evaluated. As the result, the strength decreased as the cross angle became larger. From the fracture surface observation, it was considered to be due to the friction of the contact part.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
