Question

The ends of each floor joist, beam or girder shall have not less than ____ inches of bearing on wood or metal and not less than ____ inches on masonry or concrete.

Answer 1

The question is about the bearing requirements for floor joists, beams, or girders in engineering.

Step-by-step explanation:

The question is related to the design of structures, which falls under the subject of Engineering. Specifically, the question is about the requirements for bearing on wood, metal, masonry, or concrete for floor joists, beams, or girders.

In engineering, it is important to ensure sufficient bearing to support the load. The answer to the question is dependent on the specific building codes and standards in the jurisdiction where the structure is being designed.

For example, in the International Building Code (IBC), the minimum bearing requirements for wood or metal on wood or metal may be 1.5 inches, while for masonry or concrete, it may be 3 inches.
