Formula
δ = P L³ / (3 E I)
δ: tip deflection, P: end point load
How to Use
- Enter end load P and length L.
- Enter modulus E and second moment I.
- Get tip deflection δ.
Case Studies
Steel cantilever, 100 N
P=100, L=2, E=200e9, I=1e-6 → δ≈1.33×10⁻³ m.
FAQ
Other load cases?
This is for end point load only; uniform load gives δ=wL⁴/(8EI).
