Calculation method

Calculation method

Ideal tip deflection (mm)

Small-deflection Euler-Bernoulli cantilever: δ=PL³/(3EI), θ=PL²/(2EI).

Ideal tip rotation (radians)

Small-deflection Euler-Bernoulli cantilever: δ=PL³/(3EI), θ=PL²/(2EI).

Symbols and units
a
Cantilever length (mm)
b
Tip force (N)
c
Elastic modulus (MPa)
d
Second moment of area (mm⁴)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Small-deflection Euler-Bernoulli cantilever: δ=PL³/(3EI), θ=PL²/(2EI). Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
