Mechanical advantage is the factor by which a mechanism multiplies input force to produce greater output force, quantified as MA = F_out / F_in. Its parameters: mechanical configuration (lever arm ratio, pulley count, gear ratio, incline geometry), load force, effort force, and efficiency losses from friction (coefficient of friction × normal force). The concept persists through engineering curricula, mechanical design practice, technical standards (ISO, ASME), and computational simulation.

Definition
Why it is in scope
A human-made concept describing the force multiplication achieved by machines to overcome loads, quantified as output-force-to-input-force ratio. Built to persist via engineering education, technical documentation, and computational design tools.

Mechanical advantage is maintained for the sake of engineering — its purpose is to quantify force multiplication in machine design, enabling engineers to size mechanisms and predict performance.

Which-came-first (Law 7): the lever — any stick on a pivot — predates the formal concept of mechanical advantage by millennia. Levers existed first and fed into the concept of mechanical advantage as a way to quantify their benefit.

Per Law 8 removal test: mechanical advantage IS a concept about how force is amplified by simple machines. Remove force and mechanical advantage cannot operate — its entire referent (force amplification) collapses. Object-level dependency: mechanical advantage specifically picks out force relationships, not general physics.
