What is the function of a solid rivet?

A solid rivet is primarily used to fasten two or more pieces of metal together. This method of joining is widely employed in aerospace applications because it provides a strong and permanent connection that can withstand significant loads and stresses. The rivet is inserted into pre-drilled holes in the metal pieces, and the head of the rivet is deformed (or "tail" is bucked), creating a tight bond between the materials. This secure fastening method is crucial for maintaining the integrity and strength of aircraft structures, which must endure various conditions during operation.

In contrast, fabric fastening involves different methods, such as stitching or adhesive bonding, which are not applicable to solid rivets. While structural support is a consideration in the design of riveted joints, the rivet's primary role is fastening rather than supporting weight directly. Additionally, solid rivets do not function as hinges; their design does not allow for rotational movement, which is required for a hinge mechanism. Thus, the choice focusing on the fastening of metal pieces accurately reflects the fundamental purpose of solid rivets in aerospace engineering.
