Does a glowing bridge still need structure?
Fit each assembly on its seat before starting.
The ring creates a fictional material; the bridge then obeys the declared beam model. Fit both abutments, construct and test load. Increase the section depth and compare the result with simply increasing the ring power. The supports divide the load, and the beam must stay below both strength and deflection limits.
A ring that creates load-bearing matter is fictional. A simply supported rectangular teaching beam has chosen elastic modulus 70 GPa, allowable stress 250 MPa and width 0.6 m. Point load at midspan; beam self-weight and dynamic loads omitted. The field power is an explicit invented maintenance rule: 100 W plus elastic strain energy replenished over 10 s. This is an energy input assumption, not a law of real structures. Model valid only for small deflection; a failed limit is shown without extrapolating plastic collapse.
Support at least 1,000 kg across a span of at least 6 m while staying below the stress and span/250 deflection limits.
Assemble a bridge made by a fictional power ring.
