# Cantilever under a tip load, Timoshenko deflection (hex20)

A 10 × 1 × 1 bar of hex20 elements (20 × 2 × 2) clamped at x = 0 with a total
force of 1 in −z spread over the free end (E = 1000, ν = 0, so no Poisson coupling at the clamp).
Timoshenko beam theory gives δ = PL³/(3EI) + PL/(κGA) = 4 + 0.024 = 4.024.
