What is the minimum spacing for a single row of aircraft rivets?

  1. Two times the diameter of the rivet shank

  2. Three times the diameter of the rivet shank

  3. Four times the diameter of the rivet shank

  4. Equal to the diameter of the rivet shank

The correct answer is: Three times the diameter of the rivet shank

The correct answer is option B: Three times the diameter of the rivet shank. This spacing is important to ensure the structural integrity of the joint formed by the rivets. By having a minimum spacing of three times the diameter of the rivet shank, it allows for proper load distribution and reduces the risk of stress concentrations in the structure. This spacing is a standard requirement in aircraft construction and maintenance practices to maintain safety and reliability. Options A, C, and D are incorrect because they do not provide the optimal spacing required for the proper distribution of loads and prevention of stress concentrations in the aircraft structure. Different spacing distances could compromise the integrity of the joint and potentially lead to structural failure over time.
