The Flying Blade Cut Bench: The Cut and the Filament

THE FLYING BLADE CUT BENCH · THE THREE-BODY PROBLEM CH. 31, OPERATION GUZHENG
Fifty filaments one-hundredth of a hair thick, strung across the Gaillard Cut; a sixty-thousand-ton ship sails through at the same speed, the book says
a filament that parts steel must carry the cutting force on two nearly straight segments: that tension over its area is the price
the book's net, ship and canal are reported; the hair, the steel, the strongest materials, the tanker, the canal and the air are tabulated and measured
the two cut models and Lamb's drag are established; the forces, tensions, stresses, drag and planes are exact; the lag, the plate, the speed, the members are dials
the material itself has no stated strength: every figure about it is what the scene asks, never what the book states
watch the pass · climb the ladder · open the ship's ledger · read the file

fact ⇄ what kind of claim · live

Chapter 31: two pillars, filaments about half a metre apart, 'about one-hundredth the thickness of human hair', the canal 150 m at its narrowest, the ship 31 m tall with 8 m of draught, 'Fifty ultrastrong nanofilaments, each 160 meters long', 24 m pillars, 'continued to sail forward at the same speed', 'more than forty slices, each slice half a meter thick'; chapters 4, 6 and 24 on the material

the novel's own words (Ken Liu's translation, Head of Zeus 2024); every figure on the bench starts from them

REPORTED

A human hair 17 to 181 µm, 75 nominal; IACS Grade A steel 235 and 400 to 520 N/mm²; the 60 % shear rule; mild steel 120 HB; the tensile-strength table; the Eagle S's 228.6 × 32.3 m and 11,300 kW; the Kim et al. tanker's 20.65 m depth and plates; the Cut's 12.6 km and the Authority's 192 m; Panamax 32.3 m and the 33.53 m chambers; the Authority's 8 and 6 knots; ICAO air

reference pages and tables, each named on the File

TABULATED

Nanotubes 11 to 63 GPa (Yu et al. 2000), shells above 100 GPa (Peng et al. 2008), bundles 80 GPa (Bai et al. 2018), graphene 130 GPa (Lee et al. 2008); EH36 ship steel's J of 926 kJ/m² (Zhu et al. 2021)

papers, as published

MEASURED

The two cut terms of the wire-cutting literature (a fracture term, a plastic term growing with the wire's diameter); G = K²/E; Lamb's low-Reynolds-number drag on a cylinder

textbook forms, each cited; the two cut terms are printed as bounds and never averaged

ESTABLISHED

The filament's area; τ·d·ℓ and G_c·ℓ; T = F/(2 sin θ) from the lag; the stress; the fold-back floor; the break budget 2σA; the drag per metre of net; the kerf a plane meets; drag over thrust; the planes through the hull; the chord; the contact pressure

arithmetic on the book's and the pages' figures; no constant fitted

EXACT

The hair inside its range, the material's strength, the lag, the span, the steel's grade and shear ratio, the fracture energy, the plate, the member and its skew, the wind, the speed, the ship's mass and depth, the pillar base, the crankshaft, the wrap; the cube law and thrust as P/v; the hour and the scene's staging

choices, shown as dials; every finding is quoted across their range

MODELLED

Whether the scene's price is a strength no material has, or the specification of a material the novel declines to describe

the question this bench leaves to you
