EEJ MAIN Aptitude QUESTION #10982
Question 1
The term 'cantilever' in structural engineering refers to:
  • A beam supported at both ends
  • A horizontal structural element fixed at one end and free at the other✔️
  • A diagonal brace in a frame
  • A type of arch with a keystone
Correct Answer Explanation

A cantilever is a beam or structural element that:

  • Is fixed (anchored) at one end only
  • The other end projects freely without support
  • Carries load primarily through bending (hogging moment at the fixed end)

Famous cantilever examples in architecture:

  • Fallingwater (Frank Lloyd Wright) — dramatic cantilevered terraces over a waterfall
  • CN Tower observation deck
  • Balconies, overhanging roof eaves, diving boards

The tension face of a cantilever is at the TOP (opposite to a simply-supported beam where tension is at the bottom).
