Which of the following is a possible outcome of improper rivet spacing?

Improper rivet spacing can lead to weaker joints because the integrity of the connection between the materials is compromised. Rivets are used to fasten sheets of metal together, and their spacing is critical to ensure that the load is evenly distributed across the joint. If rivets are too far apart, certain areas may experience excessive stress, leading to deformation or failure under load. Conversely, if rivets are too close together, it can lead to issues such as overlapping that might interfere with the structural integrity as well. Therefore, maintaining proper rivet spacing is essential for achieving the strength and durability required in aircraft structures.

The other outcomes listed do not align with the implications of improper rivet spacing; for example, improper spacing does not contribute to stronger bonds or improve efficiency. Instead, it could result in further complications during the manufacturing process, leading to additional time spent on corrections and inspections, thus negatively affecting production times.
