What is the appropriate length of rivet when joining 0.032-inch and 0.064-inch aluminum sheets?

To determine the appropriate length of the rivet for joining aluminum sheets of differing thicknesses, you need to consider the total thickness of the materials being joined and additional length for the rivet's grip.

In this case, with one sheet measuring 0.032 inches and the other measuring 0.064 inches, the combined thickness of the sheets is 0.096 inches. Rivets are typically chosen not only for the combined thickness but also require extra length to ensure proper deformation during the riveting process, as well as to provide a sufficient grip for securing the sheets together.

A standard rule of thumb for rivet length is to add approximately 1/16 inch to 1/8 inch to the total thickness of the sheets. When calculating the rivet length, adding around 1/8 inch (which is 0.125 inches) to the combined thickness of 0.096 inches gives us approximately 0.221 inches. This figure suggests that a length of rivet around 5/16 inches, which equals 0.3125 inches, would be appropriate to adequately accommodate the requirements of riveting in this scenario.

Thus, the correct answer indicates that a 5/16 inch rivet provides the necessary length for a
