`Container ship wire rope fracture`

Holman's consulting case on a fractured cargo-container lifting rope. Full-scale tensile test in a three-story vertical machine; broke above 300,000 lb (Holman conflates with ksi in delivery — see editorial register flag).

One of the students the other day asked about wire rope. So the same as you can do a tensile test on this material and watch it neck down — I'm going to show you a video of a case I worked on a few years ago. It was off a cargo container ship. They have wire ropes for lifting huge amounts of weight onto the container ships. One of the wire ropes fractured, and they wanted to know if it was a material issue.
