Which strand has a breaking strength of 51.1 kN (11500 lbf)?

Breaking strength is the maximum load a strand can withstand before it fails. When a problem gives a specific breaking strength, you choose the option whose rating matches that value exactly. Here, the required value is 51.1 kN, which is about 11,500 lbf. The strand rated at 51.1 kN matches this specification precisely, so it is the correct choice. The other options—26.7 kN, 29.6 kN, and 15.0 kN—are lower strengths and do not meet the given requirement. A quick unit check shows 51.1 kN is roughly 11,480–11,500 lbf, consistent with the stated conversion.
