Catenary Cable API
Catenary (hanging-cable) maths as an API, computed locally and deterministically. The sag endpoint solves the exact catenary for a cable hung between two level supports: from the span, the weight per unit length and either the horizontal tension or the sag, it returns the catenary parameter a = H/w, the sag a·(cosh(L/2a) − 1), the cable length 2a·sinh(L/2a), the minimum tension (the horizontal tension at the lowest point) and the maximum tension at the supports (H·cosh(L/2a)), plus the slack over the straight span. The parabolic endpoint gives the shallow-sag parabolic approximation — sag = w·L²/(8·H) — that is standard for overhead utility lines, and converts between sag and tension either way. The length endpoint returns the cable length for a given span and sag, with the parabolic value alongside for comparison. Forces and lengths are unit-agnostic but must be consistent (for example newtons, newtons per metre and metres). Everything is computed locally and deterministically, so it is instant and private. Ideal for power-line and transmission tools, zip-line and rigging apps, suspension and surveying calculators, and physics and engineering education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is hanging-cable catenary maths; for rigging working load limits use a rigging API and for beam deflection use a beam API.

Wire Gauge API
AWG (American Wire Gauge) maths as an API, computed locally and deterministically. The awg endpoint returns the physical properties of a gauge — the diameter, 0.127·92^((36−n)/39) mm, the cross-section area, the DC resistance per kilometre and per 1000 ft for copper or aluminium, and the Preece fusing current (the point at which the wire melts, far above any safe operating ampacity). The fromdiameter endpoint goes the other way, giving the nearest AWG for a measured diameter or cross-section area, n = 36 − 39·log₉₂(d/0.127). The resistance endpoint gives the resistance of a wire run from its gauge, length and material, R = ρ·L/A. Gauges 0/0 (1/0), 00 (2/0) and 000 (3/0) are entered as −1, −2 and −3. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics, electrical and maker app developers, wiring and cable-selection tools, and engineering education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is wire-gauge geometry and resistance; for cable voltage drop over a circuit use a voltage-drop API.

Knitting Gauge API
Knitting and crochet gauge maths as an API, computed locally and deterministically. The stitches endpoint turns a gauge — the standard stitches and rows per 10 cm measured from a tension swatch — into the number of stitches to cast on for a target width and the number of rows for a target length; at 22 stitches and 30 rows per 10 cm, a 50 cm wide by 60 cm long piece needs 110 stitches and 180 rows. The gauge endpoint works backwards from a measured swatch, converting a count over a measured distance into stitches (or rows) per 10 cm, per centimetre and per inch — 33 stitches over 15 cm is a gauge of 22 per 10 cm. The convert-pattern endpoint re-scales a pattern written for one gauge to your own gauge so the finished garment keeps its intended size: your count = pattern count · (your gauge / pattern gauge), so a 100-stitch cast-on at a 20-per-10 cm pattern becomes 110 at your 22-per-10 cm tension. Dimensions are in centimetres. Everything is computed locally and deterministically, so it is instant and private. Ideal for knitting, crochet, pattern-design, craft-marketplace and maker app developers, gauge and tension calculators, and yarn-shop tools. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is gauge and stitch maths; works for crochet too by using your stitch gauge.

Moment of Inertia API
Rigid-body rotational-inertia mechanics as an API, computed locally and deterministically. The shape endpoint returns the mass moment of inertia and the radius of gyration k = √(I/m) for a named standard body about its characteristic axis — a solid sphere (I = 2/5·m·r²), thin spherical shell (2/3·m·r²), solid cylinder or disk (1/2·m·r²), annular/hollow cylinder (1/2·m·(r1²+r2²)), thin ring (m·r²), thin rod about its centre (1/12·m·l²) or about one end (1/3·m·l²), rectangular plate or cuboid (1/12·m·(a²+b²)), solid cone (3/10·m·r²) and point mass (m·r²) — so a 2 kg solid sphere of radius 0.5 m has I = 0.2 kg·m². The parallel-axis endpoint applies the Steiner theorem I = I_cm + m·d² to shift a moment of inertia from the centre-of-mass axis to any parallel axis a distance d away. The shapes endpoint lists the whole catalog with its formulas. All quantities are SI (kg, m → kg·m²). Everything is computed locally and deterministically, so it is instant and private. Ideal for mechanical-engineering, robotics, CAD/CAE, rotating-machinery, structural-dynamics and physics-education app developers, flywheel-and-shaft design tools, and simulation software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is rotational inertia; for stored rotational energy and flywheel sizing use a flywheel API and for torque and angular acceleration a torque API.

API de Calculadora de Conicidade
Geometria de conicidade e cone como uma API, computada local e deterministicamente. O endpoint de conicidade relaciona os diâmetros grande e pequeno, o comprimento e a conicidade de uma peça cônica: forneça os dois diâmetros e o comprimento e ele retorna a razão de conicidade, a conicidade por pé e por polegada (para peças em polegadas), o ângulo incluído 2·atan((D−d)/(2L)) e o ângulo (de conicidade) metade a partir do eixo — ou deixe um dos diâmetros ou o comprimento de fora e forneça a conicidade por pé, e ele resolve para a dimensão faltante. O endpoint diâmetro-em fornece o diâmetro (e raio) em qualquer distância ao longo da conicidade, medido a partir da extremidade grande ou pequena, por interpolação linear d(x) = D − (D−d)·x/L. O endpoint morse é uma referência da série padrão de conicidade Morse MT0 a MT7, com a conicidade por pé de cada cone, diâmetro grande e pequeno na linha de calibre, comprimento e ângulo incluído. Comprimentos e diâmetros usam unidades consistentes (polegadas por padrão, ou milímetros para as saídas de ângulo e razão). Tudo é computado local e deterministicamente, então é instantâneo e privado. Ideal para aplicações de usinagem e ferramentas de torno, CAD e fabricação de ferramentas, projetos de fabricação e metalurgia, e calculadoras de engenharia mecânica. Computação local pura — sem chave, sem serviço de terceiros, instantâneo. Ao vivo, nada armazenado. 3 endpoints. Isto é geometria de conicidade; para passo de rosca e broca de rosca use uma API de rosca e para geometria de engrenagens de dentes retos use uma API de engrenagens.
