How to use

Enter the loads, the station, the overhang, the span, the modulus, and the area moment

x must lie strictly between the supports. a is the overhang; ap is each paired load distance from the nearer support.

Read the deflection

A downward overhang load lifts the span; span loads and sagging moments keep their usual signs.

Check station

P = 48, Pp = 48, w0 = 24, M = 4, a = 1, ap = 0.5, x = 1, L = 2, E = 1, I = 1

δ = δ_overhang + δ_tri + δ_paired + δ_M

δ = 2.5

Definition: A beam of span L has an overhang a beyond the right support, with load P at the overhang end, a triangular load of peak w0 on the span, a symmetric paired point load Pp at distance ap from each support (ap is not the overhang a), and one sagging end moment M on the span. Deflection at station x on the span is the sum of those elastic curves.

Outputs: delta
Formula: δ = δ_overhang + δ_tri + δ_paired + δ_M. x = L/2 recovers the listed midspan pages.
Assumptions: Calculation runs locally in the browser; values are not uploaded.
Keep units consistent with the labels on each field.
The check station recovers −12 + 2.5 + 11 + 1.
Units: The inputs set the deflection unit.
Boundary conditions: a required input missing → MISSING_REQUIRED_INPUT

Example: P = 48, Pp = 48, w0 = 24, M = 4, a = 1, ap = 0.5, x = 1, L = 2, E = 1, I = 1 → δ=2.5

Background

Interpretation and common distinctions.

Find the deflection at a stated station for this superposition: overhang tip load P, triangular on the span, paired Pp at ap, and one end moment M.

The overhang length is a. Each paired load sits ap from the nearer support (not a). The check midspan recovers −12 + 2.5 + 11 + 1.

Frequently asked questions

Key distinctions behind the calculation.

Does the check station match the landed pages?

Yes. It gives δ = −12 + 2.5 + 11 + 1 = 2.5.

Is ap the same as the overhang a?

No. a is the overhang beyond the right support. ap is the distance of each paired load from the nearer support.
