Loadpath.
Move a load and see how an idealized truss distributes its forces.
Enter the structural workshop — move a load, remove a member, follow the force ↗
A REAL SOLVER, WITH BOUNDARIES
Geometry follows
the load.
Each bar has an axial stiffness of EA/L. The solver assembles the stiffness matrix, applies the supports, and calculates displacement, member forces, and reactions. Optimization reallocates cross-sectional areas to reduce compliance, fᵀu, at a fixed material volume.
The original comparison uses the same load, geometry, and volume. Bars retain at least 0.12 mm² to preserve the analyzed connections. Colors show signed axial force; width represents area. The diagram exaggerates deformation by the displayed factor.
This is an educational, linear elastic truss model. It does not check buckling, yielding, fatigue, joint strength, self-weight, or manufacturing. Exported diagrams and analysis are study materials.

A note from Luis.
I enjoy architecture as a way to think about dependencies: a change in one place has consequences elsewhere. This idealized truss makes force paths visible. It does not certify a real structure or substitute for a physical test.

Move the load position, start the solver, and compare which members need more material.
