Types of riveted joints: When one plate overlaps the other and the two plates are riveted together with two rows of rivets, the joint is termed as what?

Introduction / Context:
Riveted joints are classified by plate arrangement (lap or butt) and by the number of rivet rows and covers. Differentiating these types is essential for computing efficiency and detailing pitch and edge distances.

Given Data / Assumptions:

• Two plates overlap directly (lap arrangement).
• There are two rows of rivets across the joint.
• No cover plates are mentioned, so it is not a butt joint.

Concept / Approach:
A lap joint uses overlapping plates connected by rivets. When there are two rows of rivets, it is designated as a double riveted lap joint. Butt joints, by contrast, use cover plates (single or double) and do not rely on plate overlap.

Step-by-Step Solution:

Verification / Alternative check:
Textbook nomenclature lists lap joints (single- or double-riveted) versus butt joints (single- or double-strap/cover).

Why Other Options Are Wrong:

• Single riveted lap joint: only one row of rivets.
• Double riveted butt joints: require one or two cover plates with aligned or staggered rows.

Common Pitfalls:
Confusing number of rows with number of covers; “double” in lap joints refers to rows, not straps.

Final Answer:
Double riveted lap joint
