When stressing barrier cable, the strand can only be stressed what percentage of the ultimate strength of the strand?

• A. 6 percent
• B. 15 percent
• C. 80 percent
• D. 100 percent

Answer: (A)

When stressing barrier cable, the correct percentage of the ultimate strength of the strand that can be used is 6 percent. This practice is governed by safety and structural integrity considerations, as stressing the cable beyond this percentage could compromise its performance and lead to failure or other catastrophic issues. The 6 percent threshold serves as a guideline to ensure that the materials maintain their mechanical properties without risking deformation or weakening under stress. It helps in maintaining a balance between obtaining the necessary strength for structural integrity and preventing over-stressing, which could lead to premature material fatigue or failure over time. Adhering to this limit is crucial in maintaining the reliability and safety of installations involving barrier cables.
