"DrollTroll" fired this volley in
:

You know the loop at the end of wire rope, with a crimped-type band,
often around an "eye", maintaining the loop?

The "eye holder thingy" is called a "thimble".

If the crimp is properly done, deforming the ferrule and embedding it
into the fabric of the wire rope, the joint is as strong as the shear
strength of the ferrule times the effective 'tooth' area, or the
tensile strength of the rope; whichever is weaker.

Try looking up the shear strength of common aluminum alloys, then
figure (say) a 1/4" wire rope having about 1/4 square inch of
effective gripping area of the ferrule embedded into the rope.
