Cantalever \Can"ta*lev`er\, n. [Cant an external angle lever a
supporter of the roof timber of a house.] [Written also
{cantaliver} and {cantilever}.]
1. (Arch.) A bracket to support a balcony, a cornice, or the
like.
[1913 Webster]

2. (Engin.) A projecting beam, truss, or bridge unsupported

{Cantalever bridge}, a bridge in which the principle of the
cantalever is applied. It is usually a trussed bridge,
composed of two portions reaching out from opposite banks,
and supported near the middle of their own length on piers
which they overhang, thus forming cantalevers which meet
over the space to be spanned or sustain a third portion,
to complete the connection.
[1913 Webster]
