How to use

1

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; ao is the offset load position.

2

Read the deflection

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

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, an offset point load Po at station ao from the left support (ao is not the overhang a). Deflection at station x on the span is the sum of those elastic curves.
What it calculates
Deflection at a stated station for this overhang-span superposition.
Inputs
  • P
  • Po
  • w0
  • a
  • ao
  • x
  • L
  • E
  • I
Outputs
  • delta
Formula
δ = δ_overhang + δ_tri + δ_offset. 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 + 5.5.
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
P = 48, Po = 48, w0 = 24, a = 1, ao = 0.5, x = 1, L = 2, E = 1, I = 1 → δ=−4

Background

Interpretation and common distinctions.

Find the deflection at a stated station for this superposition: overhang tip load P, triangular on the span, offset Po at ao.

The overhang length is a. The offset position is ao (not a). The check midspan recovers −12 + 2.5 + 5.5.

Frequently asked questions

Key distinctions behind the calculation.

Does the check station match the landed pages?

Yes. It gives δ = −12 + 2.5 + 5.5 = −4.

Is ao the same as the overhang a?

No. a is the overhang beyond the right support. ao is the span station of Po from the left support.
