Torque & Balance

Interactive simulation — adjust parameters and watch the visualization update in real time.

How it works

Static torques from point loads and a uniform beam’s weight about a chosen pivot. When the net torque is zero, the beam is in rotational equilibrium (ignoring support forces that cancel weight).

Key equations

τ_net = Σ mᵢ g (xᵢ − x_p) + m_beam g (L/2 − x_p)

Positive τ (by convention here) tends to rotate the beam one way; the canvas tilt is exaggerated for visibility only.
