What is the minimum thickness of solid blocking in conventional light-frame construction?

In conventional light-frame construction, solid blocking is used to provide structural support in various applications, such as reinforcing joints and preventing lateral movement. The minimum thickness of solid blocking is specified to ensure adequate strength and durability. The correct answer, which is 2 inches, aligns with common building practices and codes that dictate the dimensions needed for solid blocking to safely transfer loads and facilitate proper connections between framing members. This thickness allows the blocking to effectively support loads while providing a stable connection, ensuring structural integrity in the construction process.
