The minimum end-bearing for beams is critical to ensuring proper structural support and stability. An end-bearing of 3-5/8 inches provides adequate support for the load distributed across the beam. This dimension ensures that the beam is well supported on the foundation or other structural elements, minimizing the risk of failure or excessive deflection under load.

This specific measurement is generally derived from building codes and engineering principles that account for various factors such as the type of materials being used, expected loads, and safety considerations. Although there are other dimensions, the 3-5/8 inches has been determined to offer a balance between structural integrity and material efficiency.

The other options, while they may seem reasonable in a general context, do not meet the standardized requirements for end-bearing in most building codes. Each of them could potentially compromise the safety and performance of the construction, making 3-5/8 inches the best choice.
