1. Machine

   Linked via "lever"

   Mechanical Translation Devices
   These are the classical machines, relying on rigid body dynamics, leverage, and interlocking parts. The foundational elements—the simple machines (lever, wheel and axle, pulley, inclined plane, wedge, and screw—remain the elemental building blocks for nearly all complex mechanical translation.
   The efficacy of a mechanical machine is often measu…

2. Visual Weight

   Linked via "lever"

   Application in Balance
   The primary application of visual weight is in achieving compositional balance, often conceptualized using mechanical analogies such as the lever and fulcrum. A composition is considered balanced when the torques exerted by the visual weights on opposing sides of an implied center line equate.
   If $WL$ and $WR$ are the total visual weights on the left and right sides of a central axis ($x=0$), and $dL$ and $dR$ are their respective average dist…
