It depends on:
1. The section (box, I-beam, angle),
2. The cross-sectional dimensions, and
3. The width (span).
More info is needed for a useful answer.
The strength will vary depending on the type of concrete, the base, and the presence or absence of steel or fiberglass reinforcing.

If you're referring to 14 gauge steel wire, about 60-65 pounds safely, but remember, supported weight depends not only on the wire, but the screws and nails that are attached to the object and the wall or ceiling. (Not to mention the material of the wall or ceiling. Drywall will hold much less than hardwood, so use a stud finder if possible to drill/nail into the wall or ceiling for added support) When in doubt, always use stronger, thicker materials than you think you'll need.
To figer that out, well it is hard. you would have be a geart geomiter or bulider. some steel bridges are pritty old so yeh.
Higher contents of carbon make the steel harder but more brittle. The harder steel will cut better and hold an edge longer but has much less shear strength.

It can hold upto 60tons, depending on the quality of the product and type of steel weigh bridge you've picked.
There is no listed maximum weight that this can hold, but it is made of steel and is very sturdy. The tray is intended for 20 dumbbells.
Given the same construction materials (originally stone) an arch is tremendously stronger than a post and lintel. You can pile much more weight on an arch without causing it to collapse, as compared to the post and lintel; the lintels break much more easily.
it can't hold very much weight
The strength will vary depending on the type of concrete, the base, and the presence or absence of steel or fiberglass reinforcing.
It depends on the bridge.

Without knowing how the roof was constructed and with what dimension of lumber or steel, there is no way to estimate.

That depends... on the composition of the steel !
well a steel sword can very in weight. But i bet it is very heavy.
