Archetype Sub-90 Dry-Wipe Invariant (Equilibrium of Coplanar Forces, Drag/Terminal Velocity Balancing & Tension-Spring/Pulley Systems): In static or dynamic equilibrium (at rest or constant terminal velocity), net force in every direction is zero: upward tension/drag balances downward weight (T = mg or F(drag) = mg), and pulley rope tension is uniform throughout a frictionless massless cord.
