As a reminder, OMS has a new feature on its website called Ask OMS.  The purpose of Ask OMS is for you to post your questions related to architecture, and then we’ll provide the answers.  To help in answering questions we often get asked, we’re providing terminology definitions.  This week’s word is cantilever.

Definition:  A horizontal projection (e.g., a step, balcony, beam or canopy) supported by a downward force behind a fulcrum.  It is without external bracing and thus appears to be self-supporting or “floating.”
