Code allows cantilever spans of 24 inches for every 1 inch of beam depth. For a 9 inch beam, what is the allowable cantilever span?

Explanation:
The allowable cantilever is directly proportional to the beam depth, at 24 inches per 1 inch of depth. For a 9-inch beam, multiply: 9 × 24 = 216 inches, which equals 18 feet. So the cantilever span can be 18 feet. (Other values would require different beam depths to match those spans.)
