Engineering calculators (Beta)
Find the required moving force and power from mass, slope, friction and speed.
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.
N = mg cosθ, F = ma + mg sinθ + μk N, Fstart = max(0, mg sinθ + μs N), Pdrive = Fv/η (F≥0), Pbrake = −Fv (F<0), Twheel = Fr
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.

何kgのものを、どの勾配・摩擦・速度で動かすかから必要な力と動力を求めます。
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。
N = mg cosθ, F = ma + mg sinθ + μk N, Fstart = max(0, mg sinθ + μs N), Pdrive = Fv/η (F≥0), Pbrake = −Fv (F<0), Twheel = Fr
直線上を正方向へ走行し、駆動力は路面と平行に作用するモデルです。勾配は角度・rad・%を切り替えられます（5%は5°ではありません）。μは接触条件に合わせて入力し、このモデルではμs≥μkです。始動欄は静摩擦の境界で、加速分は含みません。走行中は動摩擦を使用します。駆動力が負なら正方向へ進むために制動が必要です。制動の回生効率は扱いません。車輪の転がり抵抗・空気抵抗・回転慣性・伝達比は別途。トルクは駆動輪での値で、モーター軸ではありません。
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。
Find the required moving force and power from mass, slope, friction and speed.
The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.
N = mg cosθ, F = ma + mg sinθ + μk N, Fstart = max(0, mg sinθ + μs N), Pdrive = Fv/η (F≥0), Pbrake = −Fv (F<0), Twheel = Fr
Straight positive-direction travel with drive force parallel to the surface. Switch between degrees, radians and grade percent (5% is not 5°). Enter coefficients for the actual contact; this model requires μs≥μk. Breakaway is the static-friction threshold without acceleration; running force uses kinetic friction. Negative drive force requires braking during forward travel. Regeneration efficiency, wheel rolling resistance, drag, rotational inertia and gearing are excluded. Torque is at the drive wheel, not the motor shaft.
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.
