Final answer:
Mechanical connections use nuts and bolts, screws, nails, rivets, and similar devices to transfer load through attached elements.
Step-by-step explanation:
Connections that use nuts and bolts, screws, nails, rivets, and similar devices to transfer load through attached elements are called Mechanical connections. These connections rely on mechanical forces to hold the elements together, such as the friction between the nuts and bolts or the compression caused by screws. They are commonly used in various engineering applications, including construction, manufacturing, and mechanical design.
