🔍 Key Concepts

• Stress distribution between rivets and welds when both are used on the same connection • Effects of peening/hammering during riveting on nearby welded joints • Behavior of welded joints under shock or deformation compared with riveted joints

💭 Think About

• When you drive and peen a rivet, what kind of forces and vibrations are introduced into the joint, and how might those affect a nearby weld? • In a combined riveted–welded joint, does the weld usually make the plate more likely to tear, or is there another weaker point that tends to fail first? • Think about whether a weld would typically increase or decrease the load carried by each rivet, and what that implies for the stress on the rivet heads.

✅ Before You Answer

• Identify which statement matches the idea that hammering/setting rivets can introduce high local stresses and distortion. • Check which choices incorrectly assume that welds always strengthen everything without side effects. • Eliminate any option that suggests a failure mode that is less likely than damage to the weld itself in a mixed rivet–weld connection.
