Calculation method
Calculation method
Left reaction (kN)
Moment equilibrium gives reactions; evaluate piecewise-linear moment at supports and load positions.
Right reaction (kN)
Moment equilibrium gives reactions; evaluate piecewise-linear moment at supports and load positions.
Positions and moments (JSON)
Moment equilibrium gives reactions; evaluate piecewise-linear moment at supports and load positions.
Symbols and units
- a
- Simply-supported span (m)
- b
- Downward point loads (kN)
- c
- Load positions from left support (m)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Moment equilibrium gives reactions; evaluate piecewise-linear moment at supports and load positions. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
