How to use
Enter the peak intensity, the uniform intensity, the point load, the station, the length, the modulus, and the area moment
x must lie strictly between the supports.
Read the deflection
The signs of w0, w, and P are the signs of their parts of δ.

- Definition
- The beam carries an end-peaked triangle, a uniform load, and a midspan point load. Deflection at x is the sum of those elastic curves.
- What it calculates
- Deflection at a stated station for an end-peaked triangle, a uniform load, and a midspan point load.
- Inputs
- w0
- w
- P
- x
- L
- E
- I
- Outputs
- delta
- Formula
Sum of the triangle curve, the uniform curve, and the point-load curve.- Assumptions
- Calculation runs locally in the browser; values are not uploaded.
- Keep units consistent with the labels on each field.
- The check station recovers 6.8 + 8.
- Units
- w0, w, P, x, L, E, and I set the deflection unit.
- Boundary conditions
- missing w0, w, P, x, L, E, or I → MISSING_REQUIRED_INPUT
- L ≤ 0, E ≤ 0, or I ≤ 0 → VALUE_MUST_BE_POSITIVE
- x ≤ 0 or x ≥ L → INVALID_INPUT
- Example
- w0=24 w=24 P=48 x=1 L=2 E=1 I=1 → δ=14.8
- Validation cases
