Tensão axial, deformação e módulo de Young como uma API, calculados local e deterministicamente. O endpoint de tensão relaciona as três grandezas de um membro carregado axialmente — a tensão σ = F/A, a deformação ε = ΔL/L e o módulo de Young E = σ/ε — e resolve para qualquer uma que você omitir, tomando o módulo diretamente, em gigapascals, ou de uma tabela de materiais embutida (aço, alumínio, cobre, titânio, concreto, vidro e mais), com a tensão reportada em pascals, MPa e GPa. O endpoint de alongamento calcula o quanto uma barra se estica sob uma carga axial, δ = F·L/(A·E), a partir da força, comprimento e seção transversal (área ou diâmetro) e do material ou módulo, juntamente com a tensão, deformação e a rigidez axial k = A·E/L. O endpoint de Poisson trabalha com o coeficiente de Poisson ν: a deformação lateral que acompanha uma deformação axial, e o módulo de cisalhamento G = E/(2(1+ν)) e o módulo volumétrico K = E/(3(1−2ν)) derivados do módulo de Young. Tudo é calculado local e deterministicamente, portanto é instantâneo e privado. Ideal para ferramentas de engenharia mecânica, civil e de materiais, aplicações de projeto estrutural e de máquinas, testes de materiais e educação. Cálculo local puro — sem chave, sem serviço de terceiros, instantâneo. Ao vivo, nada armazenado. 3 endpoints. Esta é a deformação axial de materiais; para o estado 2D de tensão (tensões principais, círculo de Mohr) use uma API de círculo de Mohr e para flambagem de colunas use uma API de flambagem.

Thermal-expansion maths as an API, computed locally and deterministically. The linear endpoint computes how much a solid grows or shrinks when its temperature changes, ΔL = α·L0·ΔT, returning the change in length and the new length from an original length, a temperature change (given directly or as an initial and final temperature) and the linear expansion coefficient α — taken from a built-in material table (steel, aluminium, copper, concrete, glass, invar and more) or supplied directly; lengths accept metres, centimetres, millimetres, feet or inches. The volume endpoint computes volumetric expansion, ΔV = β·V0·ΔT, where for a solid the volumetric coefficient is β ≈ 3α and for a liquid (water, ethanol, mercury, petrol and others) β is taken directly; volumes accept cubic metres, litres, millilitres or cubic feet. The materials endpoint lists the coefficients. A negative temperature change gives contraction. Everything is computed locally and deterministically, so it is instant and private. Ideal for civil and mechanical engineering tools, rail, pipe and bridge expansion-gap design, manufacturing-tolerance and HVAC apps, and physics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is thermal expansion; for heat energy and temperature change use a specific-heat API.

Metal stock weight and cost as an API, computed locally and deterministically. The weight endpoint computes the mass of a length of metal stock from its shape, dimensions and material: round bar, square bar, flat bar or plate, sheet, hexagonal bar, round tube or pipe and rectangular (box) tube. It works out the cross-sectional area, multiplies by the length and the material density, and returns the weight per piece and the total for a quantity — in kilograms, pounds, grams and tonnes — along with the volume. Material density is looked up from a built-in table of metals (steel, stainless, aluminium, copper, brass, bronze, lead, zinc, titanium, nickel, gold, silver and more) or you can pass an explicit density. The cost endpoint multiplies that weight by a price per kilogram, pound or tonne to give the material cost per piece and in total. The materials endpoint lists the densities. Dimensions accept millimetres, centimetres, metres, inches or feet. Everything is computed locally and deterministically, so it is instant and private. Ideal for metal fabrication and machine-shop tools, engineering and CAD apps, scrap and stock quoting, and shipping-weight estimates. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is metal stock weight from geometry and density; for beam reactions and deflection use a beam API and for live metal spot prices use a commodities API.
