13. This architectural feature makes me nervous. What is a cantilever?
From Quiz Architectural Terms
Answer:
A beam or external construction anchored at only one end
Minor examples of a cantilever are a flagpole jutting from the side of a building, or a diving board. On a larger scale, however, examples of cantilevers at work include some bridges without pylons, or the balcony on Frank Lloyd Wright's unique Fallingwater house, or those skywalks that jut out over sheer drops below, such as the one at the Grand Canyon. Cantilevers, they assure us, are perfectly safe, because the load they carry is forced back against the side of the building. Forced back against the side of the building is right where I'd be, believe me, physics or no physics.
