The truss consists of beams with sections:

  • for the ———-, ring fingers \(R=0.05\), \(\mathrm{ep}=0.02\)

  • for ———-, circulars \(R=0.05\)

  • for ———-, circulars \(R\mathrm{=}0.07\)

Point \(A\) is in the middle of the final stem.

1.2. Material properties#

Isotropic linear elastic material:

\(E\mathrm{=}1.962\mathit{E11}\mathit{Pa}\); \(\nu \mathrm{=}0.3\)

1.3. Boundary conditions and loads#

The base of the mesh is embedded.

Loading

Vertical nodal force in \(A\):

\({F}_{y}\mathrm{=}–20E6N\)

Gravity field (next \(x\) )

\(g\mathrm{=}–9.81m\mathrm{/}{s}^{2}\)
