Controls

A finite-element truss under a tip load. Members are colored by axial force; the shape shows the (scaled) deformation.

Governing equation

K u = F, k_{e} = \frac{E A}{L}, F_{y} = - 20 (11 members)

Reading this result: A 20-unit tip load drives a peak member force of 0.0. Linear FEA is linear: double the load and both the deflection and every member force double exactly. The 20x slider only magnifies the true (tiny) displacement so you can see it.
