Yes. In technical contexts, it is common to say 'to cantilever a beam' or 'the floor is cantilevered over the void'.
A bracket is a general support, often L-shaped and braced, while a cantilever is a specific engineering principle where a rigid beam is anchored at one end to support a load at the other, often without visible bracing.
No. It is a specialized technical term from engineering and architecture. Most people would understand it as 'a part that sticks out without visible support' but wouldn't use it in daily conversation.
