Specifically, this is an analysis of the strength of anchors built with cams. 'Anchor' in the title is relevant, but the title here leaves out critical information, because the overwhelming majority of anchors in rock climbs are bolted. "An Elastic Model of the Holding Power of Gear Anchors in Rock Climbing" would be much more apt (though gear anchors can include several other types of protection, "Cam Anchors" is not something I've ever heard) edit: upon further reading, you're right. There's no mention of anchors in the article, other than referring to a cam placement as 'a type of anchor'. It seems that the article was not written by climbers, which is surprising.
