Torque & Balance

This interactive simulator explores Torque & Balance in Classical Mechanics. Beam on a fulcrum. Place weights to balance or tip. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Suited to beginners and first exposure to the topic. Typical context: Classical Mechanics.

Key terms

  • torque
  • balance
  • torque balance
  • mechanics
  • classical

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.
