Cantilever is defined as

• A. Cantilever
• B. Simple span
• C. Continuous span
• D. Cable-stayed

Answer: (A)

A cantilever is a structural member fixed at one end and extending beyond its support without additional bracing along its length. This fixed end provides the reaction for the loads carried by the overhanging portion, so the member can project past the support without needing a second support at the free end. This differs from a simple span, which is supported at both ends; a continuous span, which runs over internal supports and is not fixed at a single end; and a cable-stayed arrangement, which uses cables and towers to support the deck rather than a fixed-end beam carrying overhanging load.
