Guided Atwood Machine
m1 m2 pulley

One shared sign convention

This guided problem locks the kinematics so one scalar means the same system motion everywhere: moves up, moves down, and the pulley rotates clockwise.

  • Generate one equation from each object panel. The equations are local, but the sign convention is global.
  • The force/torque equations come from the panels. The no-slip coupling equation comes from the assumptions step.
  • This version uses known and so the workspace can focus on the rotational coupling, not the inertia derivation.
