junk fun - 12/1/2023 14:10 The difference is the difference between a farmer and an engineer.

Really? Are you an engineer?

The wood works best in compression, and the wire works in tension, look at a corner post brace.

Look at a wood truss. Bottom cord is in tension

The wood brace will get a little wear in the nails or screws and sag and have no way to adjust if it's in tension. In compression it will be solid.

I'd think the wear would be the same in pull or push. Either way the strength of the connection should NOT be in the shear strength of the fastener, but in the compression of the fastener squeezing the two surfaces together.

The difference is the connections, as that university bridge in Florida should have paid a little better attention to.

Not going to look that up and I don't remember what failed on that.

Or am I misunderstanding the question? I assume you mean a 2x6 piece of lumber by "2x", did you mean something else by "2x"?

Yes! 2X4, 2X6,...wood brace
