Formulas

Core equations used by this calculator.

Deflection at xδ = δ_load(x) + δ_moments(x)

iThe check station recovers 10.5 + 8.

How to use

1

Enter the loads, the end moment, the station, the length, the modulus, and the area moment

x must lie strictly between the supports.

2

Read the deflection

The signs of the loads are the signs of their parts of δ.

Check station

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

δ = δ_load(x) + δ_moments(x)

δ = 18.5

Definition: The beam carries a one-sided triangle, a midspan point load, and equal end moments. Deflection at x is the sum of those elastic curves.
What it calculates: Deflection at a stated station for a one-sided triangle, a midspan point load, and equal end moments.
Inputs: w0
P
M
x
L
E
I
Outputs: delta
Formula: Sum of the load curve and the equal-end-moments 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 10.5 + 8.
Units: The inputs set the deflection unit.
Boundary conditions: a required input missing → 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=18.5
Validation cases: 2 published on this page
w0 = 24, P = 48, M = 16, x = 1, L = 2, E = 1, I = 1 → δ=18.5
x=0 → INVALID_INPUT
