Cable with Multiple Concentrated Loads
Create a polygonal funicular cable and inspect the force in every straight segment.
Tension only
Model distinction: point loads create straight polygonal segments; load uniform per horizontal metre creates a parabola; self-weight uniform per cable metre creates a catenary. These models are never silently substituted for one another.
The prescribed sag is measured below the support chord at the first load location, x=10.00 m.
Horizontal component H
28.00 kN
Maximum tension
32.25 kN
Left vertical component
14.00 kN
Right vertical component
16.00 kN
remains constant through every segment, while changes with segment slope. A negative free-support reaction is reported as a hold-down requirement rather than accepted silently.
Model scope and verification
Use the displayed units and idealizations, then verify the governing balance or compatibility equation before interpreting the result.
