Тест 1.13 Rod on an elastic base

Analytical solution: w = -qx/(C₁q), M = 0, Q = -C₂q/(C₁l).

Geometry:

l = 10 м; I = 2 x 10-6 м4; A = 0.003 м2; shear area F = 0.0025 м2.

Material characteristics: Е = 2.1 х 10⁷ t/m², G = 7.875 x 10⁶ t/m².

Boundary conditions: Elastic base: С1=500 t/м², С2=100 т;.
uA = uВ = 0.

Stresses: q = 50 т/м, Р2 = -Р1 = 1 т.
