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 machines by principle, type, mechanical advantage, safety and regulation, and route machinery accidents to emergency help.

A device that uses energy to apply forces and perform work or control motion, from simple machines such as the lever, wheel and axle, pulley, inclined plane, wedge and screw to complex powered machinery in industry, agriculture and homes.

What it is for: Doing work more easily, quickly or precisely.

It can be explain simple machines and mechanical advantage; classify powered machinery; find machinery safety rules and guarding requirements; understand CE marking for machinery.

Distinguishing features

Transmits or converts energy

Has moving parts

Provides mechanical advantage

Regulated for safety

What it looks like

Assemblies of moving parts, frames, motors, gears and controls.

How it is recognised

Levers, gears, belts and motors

Guards and emergency stops

Hand tools without mechanisms are simpler devices

  2. Which museums show them? provenance

What the second pass must settle

  • Should machine types be separate entries?
  • How should safety standards be linked?
  • How should historical machines be linked?
