What is the maximum length (in inches) of a structural steel member penetration?

A. 2
B. 3
C. 4
D. 5

The correct answer is: C. 4

The maximum length of a structural steel member penetration is established primarily to ensure safety and maintain structural integrity. A penetration exceeding a certain length can compromise the strength and stability of the steel member, leading to potential failure under load. In this case, the maximum penetration length of 4 inches is set to limit how much material can be removed from a structural element without significantly affecting its load-bearing capacity. This standard is crucial in construction practices to ensure that the design specifications align with safety protocols established by engineering guidelines and building codes. The context of the other options, being shorter lengths, does not provide the fullest allowance for penetrations based on current safety practices and engineering assessments. Therefore, the choice of 4 inches as the maximum length balances safety with practical architectural needs.
