The term can also refer to similar supporting structures in other contexts, such as in furniture or mechanical assemblies.

FAQ
Frequently Asked Questions
No, they are similar but distinct. A king post is the central vertical member in a simple king post truss, connecting the apex to the tie beam. A crown post is also vertical and central but supports a horizontal crown plate, which then supports the principal rafters; it's typical in more complex medieval roof structures.
It is highly unlikely unless you are discussing historic building construction. It is a specialist technical term.
Its primary function is structural: to transfer the load from the crown plate (and thus the principal rafters) down to the tie beam, helping to prevent the roof from sagging or spreading.
Rarely in standard modern construction, which uses different engineering principles. They are used almost exclusively in the restoration of historic buildings or in new builds that deliberately replicate traditional timber-framing techniques.
