Engineering calculators (Beta)
Superpose point, uniform and self-weight loads to obtain required section properties.
Click the grid to add ordered vertices. Edit coordinates in mm; separate holes with a blank line. The last vertex closes to the first automatically.
Choose units and enter numbers. Full-width digits and fractions such as 1/8 or 1 3/8 are accepted. Changing a unit converts the entered value.
Reference calculation only. Results do not certify suitability for an actual design or its safety.
Inputs: select a blue symbol to edit Results: red-orange values and lines
3D shows an illustrative extrusion. Its display length does not enter the section calculations. Edit dimensions in 2D.
qtotal=q+λg; δ=δpoint+δudl; Ireq=Iδ/δlimit; Zreq=Mmax/σallow
Displayed values are rounded. Diagrams illustrate the calculation conditions. Initial material and fluid properties are examples; replace them with values for the actual material, temperature and conditions.
ReferenceEquations assume particular loads, supports and deformation ranges. Check inputs, units and the applicability of each equation. Diagrams explain conditions; they are not manufacturing drawings or proof of safety.
Material values are typical values or reference ranges, not certified product properties or ready-to-use design allowables. They vary with standards, product form, dimensions, temper and temperature. Check the specifications and inspection certificates for the actual product.
Displayed safety factors and checks apply only to the supplied inputs and calculation model. They do not automatically establish the safety of a complete design, including code compliance, service life, fatigue or joints. For actual design, manufacture and use, separately verify applicable regulations and standards, product specifications, and the necessary tests and engineering review.

集中荷重と等分布荷重・自重を重ね、必要な断面特性を求めます。
選択した形状・計算方法により、使う項目は変わります。実際の計算は上の図と入力欄で行えます。
qtotal=q+λg; δ=δpoint+δudl; Ireq=Iδ/δlimit; Zreq=Mmax/σallow
一定断面・線形弾性・小変形。荷重は全て下向きで、単純支持は中央、片持ちは先端の集中荷重です。任意位置の複数荷重・固定梁・せん断変形はこの画面では未対応。
現在選択中の方法には、操作欄の「計算式・適用条件」を使ってください。参考計算であり、設計全体の安全性を保証するものではありません。
Superpose point, uniform and self-weight loads to obtain required section properties.
The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.
qtotal=q+λg; δ=δpoint+δudl; Ireq=Iδ/δlimit; Zreq=Mmax/σallow
Prismatic linear-elastic small-deflection beam. All loads act downward; point load is at centre for simple supports or at tip for a cantilever. Arbitrary point-load sets, fixed-fixed beams and shear deformation are excluded.
The displayed formula and conditions in the working panel apply to the currently selected model. Reference calculation only; it does not certify a complete design.
