Formulas

Core equations used by this calculator.

Deflection at xδ = δ_point(x) + δ_moment(x)

iThe check station recovers 9.8 + 4.

How to use

1

Enter the triangle intensity, the point load, the end moment, the station, the length, the modulus, and the area moment

x must lie strictly between the supports and is measured from the unloaded end.

2

Read the deflection

The signs of w0, P, and M are the signs of their parts of δ.

ϟ

Check station

w0 = 24, P = 48, M = 16, x = 1, L = 2, E = 1, I = 1

δ = δ_point(x) + δ_moment(x)

δ = 13.8

Definition: The beam carries an end-peaked triangle, a midspan point load, and one end moment. Deflection at x is the sum of those elastic curves.
What it calculates: Deflection at a stated station for an end-peaked triangle, a midspan point load, and one end moment.
Inputs: w0
P
M
x
L
E
I
Outputs: delta
Formula: Sum of the end-point curve and the one-end-moment 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 9.8 + 4.
Units: w0, P, M, x, L, E, and I set the deflection unit.
Boundary conditions: missing w0, P, M, 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 P=48 M=16 x=1 L=2 E=1 I=1 → δ=13.8
Validation cases: 2 published on this page
w0=24 P=48 M=16 x=1 L=2 E=1 I=1 → δ=13.8
x=0 → INVALID_INPUT
