A machine element is a mechanical component manufactured to perform a specific, well-defined function within a larger machine or mechanism. Standard types include: gears (torque transmission), cams (motion conversion), bearings (friction reduction), shafts (power transmission), springs (energy storage), and linkages (motion coupling). Parameters: (1) functional role — the transformation of force, motion, or energy it provides; (2) material specification — engineered from metals, polymers, or composites to withstand operational stresses; (3) geometric precision — tolerances defined by engineering standards for interoperability with other elements. Persistence mechanism: physical endurance through material science and heat treatment, maintained by replacement schedules in service.

Definition
Why it is in scope
A human-made mechanical part designed to perform a specific function within a machine or mechanism: gears, cams, shafts, bearings, springs, linkages. Built to persist through repeated cycles of stress and motion within engineered systems. Manufactured from matter to extend human capacity for force transformation and motion control.

Machine elements are built and maintained for the sake of mechanisms — their designed purpose is to serve as functional building blocks within mechanisms. Law 8d: for whose sake? Machine elements point at mechanisms as their master. Without machine elements, mechanisms cannot exist; remove machine elements and mechanisms cease to operate.

A cam IS a specific type of machine element — a rotating mechanical component with a specific function (converting rotational to linear/oscillatory motion) within a larger mechanism. Per Law 9: a competent engineer would classify a cam as a machine element. This replaces the rejected simple-machine classification; machine-element is the correct nearest kind. Law 3a: the kingdom has no bottom — machine-element is a valid construct.

A screw IS a specific type of machine element — a cylindrical component with helical ridges that performs a specific function (fastening or motion conversion) within a machine or assembly. Per Law 9: a competent engineer would classify a screw as a machine element. This is compatible with its accepted DERIVED_FROM inclined-plane edge — the screw is an application of the inclined plane principle, implemented as a machine element.

A gear IS a specific type of machine element — a rotating component with teeth that transmits torque. Files against machine-element as the nearest kind (my prior INSTANCE_OF→ simple-machine was struck; machine-element is the correct rung).

An actuator is a specific kind of machine element: a component that converts energy (electrical, hydraulic, pneumatic) into mechanical motion. Following Law 9, is-a-specific-kind-of maps to INSTANCE_OF. This parallels gear→machine-element accepted earlier.

Spring IS a machine element: a component that stores and releases mechanical energy through elastic deformation. Per Law 9, specific→general INSTANCE_OF maps correctly. The nearest kind above spring is machine-element (the class of components within machines).

A loom is a specific kind of machine-element — a device that performs a specific mechanical function in textile production. A loom transforms thread into fabric through the mechanical interlacing of warp and weft. Files against the nearest kind: machine-element.
