the claim

Resonance caused the Tacoma Narrows Bridge collapse.

REFUTED
the evidence says no
Recorded sources
0 sources for · 7 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that resonance caused the Tacoma Narrows Bridge collapse?

No. Multiple engineering and physics sources state the Tacoma Narrows Bridge collapsed due to aeroelastic flutter (self-excitation), not resonance, and note that the resonance explanation is an oversimplification found in textbooks.

The demise of the Tacoma Narrows bridge was casused by aeroelastic flutter. But isn't that just a special case of resonance?
