Cog

Cog is a small toothed gear item used to engage and transmit motion between rotating objects. It functions as a basic mechanical component within the game's crafting system and appears wherever mechanical assemblies or craftable machines are assembled. The Cog’s primary in-game role is to mesh with other rotating parts and enable the transfer or redirection of rotational motion; it is explicitly marked as usable in crafting recipes for items that require moving parts.

As a crafting component, the Cog is a fundamental element for any recipe that involves mechanical function. It is referenced across multiple language localizations as a toothed wheel designed to interlock with spinning pieces, and all versions indicate that it is consumed or incorporated during manufacturing. Because the Cog's purpose is to connect spinning elements, it is commonly required in recipes that construct or repair devices with moving gears, rotating shafts, or any mechanism that depends on torque transmission.

Practical notes for use:

• Use Cogs whenever a crafting recipe lists “Cog” or a gear-type component; they serve as the mechanical link between rotating parts.
• Place Cogs where two or more rotating elements need to be meshed; they act as intermediary teeth that allow motion to propagate through a mechanism.
• Cogs are a core component for building or upgrading mechanical devices; preserve them for recipes that explicitly require gear-like parts.
• The Cog’s function is strictly mechanical: it enables engagement and motion transfer rather than providing power, energy storage, or electronic functionality.

Do not confuse the Cog with non-mechanical components; its descriptions in different locales consistently emphasize its role as a toothed gear for meshing rotating objects and its use in crafting. Use Cogs when constructing assemblies that must transmit rotational movement or when recipes call for a gear to complete a mechanical design.
