Plural of fulcrum; multiple pivots, supports, or the points around which a lever turns.
Latin plural of 'fulcrum,' originally meaning 'the staff of a couch' or 'prop,' evolved to mean any supporting or pivoting point in both mechanical and metaphorical contexts.
The same Latin word that described the prop of a Roman couch became the technical term for how levers work—one of history's oldest technologies, yet Archimedes needed the precise vocabulary of physics to explain its power.
