machine element
Let an agent explain machine elements, relay categories, functions, standards and design considerations from mechanical engineering sources, and distinguish machine elements from assemblies and machines as a whole, structural members, electronic components and simple machines in physics teaching.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain machine elements, relay categories, functions, standards and design considerations from mechanical engineering sources, and distinguish machine elements from assemblies and machines as a whole, structural members, electronic components and simple machines in physics teaching.
A basic mechanical component used as a building block of machines, including fasteners such as bolts, screws and rivets, joining elements such as keys, splines and couplings, bearings and bushings, shafts and axles, gears, belts, chains and pulleys for power transmission, springs, seals and brakes and clutches; machine elements are standardised in dimensions and ratings by bodies such as ISO, DIN and ANSI, and their design is taught in machine design courses using methods for strength, fatigue, wear and lubrication.
What it is for: Building and transmitting power in machines.
It can be explain categories and functions; relay standards; describe design considerations; distinguish related concepts.
Distinguishing features
Standardised
Reusable across machines
Load and motion functions
Designed for life and reliability
What it looks like
Bolts, gears, bearings, springs, shafts and seals, often standardised parts.
Physical character
standards bodies: ISO, DIN, ANSI and others list
failure modes studied: fatigue, wear, corrosion list
registry parents: nonbiological component, technological component note
How it is recognised
Basic mechanical component
Machine element, mechanical component, machine part
