Torque & Balance

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.
