Quick guide
How to use this calculator
- Choose the analysis mode that matches the physical model before entering values.
- Enter properties, geometry, loads, states and coefficients from one consistent unit and sign convention.
- Use the intermediate outputs to audit the relationship, then retain the stated idealization before applying it.
Calculation method
Transparent engineering model
Equilibrium determines reactions; at a cut, V and M follow the signed forces and moments to one side. Piecewise samples expose shear and bending-moment diagrams.
The calculator evaluates only the declared relationship and preserves visitor-entered assumptions rather than selecting materials, factors, components or standards.
Worked example
Worked example
A 6 m simple beam with a 12 kN load at 2 m and a 3 kN/m full-span load gives 30 kN total load, 17 kN left reaction and 13 kN right reaction.

Supported inputs
Precision and limits
Analysis, not approval
Ideal Euler beam statics only. Supports, load paths, signs and units must be verified; results do not establish capacity or code compliance.
Standards and properties
Material properties, allowable values, load combinations, safety factors, correlations, manufacturer data, codes and jurisdictional requirements are not supplied automatically.
Units and precision
Use one consistent unit basis. Results retain working precision but cannot be more accurate than the entered measurements and properties.
