Engineering calculators (Beta)
Estimate additional mass at a stated location against a rightward lateral force on a level floor.
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.
mb=max(0,[kFh−mg(B/2−x)]/[g(B/2−xb)]).
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.

水平床上の右向き横荷重に対し、指定位置に追加する質量の目安を求めます。
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。
mb=max(0,[kFh−mg(B/2−x)]/[g(B/2−xb)]).
床は水平、右側接地端まわりの静的な比較です。元と追加質量の重心は接地範囲内に置きます。kは使用条件から選ぶ倍率で、法令や規格の安全率を自動で選ぶものではありません。滑り、逆向き荷重、床・脚・ウエイト固定部の強度、追加質量の落下防止は別に確認します。
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。
Estimate additional mass at a stated location against a rightward lateral force on a level floor.
The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.
mb=max(0,[kFh−mg(B/2−x)]/[g(B/2−xb)]).
Level floor, static comparison about the right contact edge. Both CG positions must lie within the footprint. k is user selected, not an automatically chosen code safety factor. Sliding, reversed loads, floor/leg/attachment strength and retention of the added mass require separate checks.
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.
図で条件を整理してから計算し、最後に実際の部品仕様を確認します。
Understand conditions with diagrams, calculate, then verify actual specifications.
