[BC] Clevis photo

[RichardBJohnson at comcast.net]

It's interesting I was writing about a catenary support of a tower this morning, which will always sag and act like a spring. The straightest and tautest wire, bolt, or other support will always deflect when a force is applied at right angles to its supports. This is bacause the deflecting force tends towards infinity for something perfectly straight --the same reason a horizontal wire will ALWAYS sag.

In this case, the through-bolt of the clevis has been deliberately bent by the manufacturer to keep the bending moments within the allowed stresses of the material.

Cheers,

Is it possible that some of us may have missed Jerry Mathis' reply to this with a photo of a brand new one?
