Mixed Dimensional Coupling
Prove that coupling of different dimensional elements doesn't affect the results. A cantilever with a rectangular cross-section is fixed at one end and loaded at the other with concentrated forces. Neglecting it's self-weight and assuming only small deformations, determine cantilever's maximum deflections.
