Formulas

Core equations used by this calculator.

Deflection at xδ = δ_triangle(x) + δ_distributed(x)
ix = L recovers the triangle tip page plus w a³ (4L − a)/(24 E I).

How to use

1

Enter the peak intensity, the uniform intensity, the extent, the station, the length, the modulus, and the area moment

x may reach the free end. a lies on the cantilever.

2

Read the deflection

The signs of w0 and w are the signs of their parts of δ.

Example calculations

Common configurations with formula and result.

ϟ

Free end

w0 = 24, w = 24, a = 1, x = 2, L = 2, E = 1, I = 1

δ = δ_triangle(x) + δ_distributed(x)
δ = 19.8

Definition
A cantilever carries a triangle that peaks at the wall and a uniform load w from the wall to a. Deflection at x is the sum of those two elastic curves.
What it calculates
Deflection at a stated distance from the wall for a wall-peak triangle plus a partial uniform load.
Inputs
  • w0
  • w
  • a
  • x
  • L
  • E
  • I
Outputs
  • delta
Formula
Sum of the triangle curve and the distributed curve.
Assumptions
  • Calculation runs locally in the browser; values are not uploaded.
  • Keep units consistent with the labels on each field.
  • x = L recovers the triangle tip page plus w a³ (4L − a)/(24 E I).
Units
  • w0, w, a, x, L, E, and I set the deflection unit.
Boundary conditions
  • missing w0, w, a, 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 a=1 x=2 L=2 E=1 I=1 → δ=19.8

Frequently asked questions

Key distinctions behind the calculation.

Does the free end match the two tip pages?

Yes. x = L gives δ = 12.8 + 7 = 19.8 for w0 = 24, w = 24, a = 1, and L = 2.
