Define the following: Rivet

Hint The above problem is based on the concept of mechanical fastening. The devices used for the joining of one mechanical element to another element are called the mechanical fasteners. The mechanical fasteners may be of two types. First is the temporary fastener and second is the permanent fastener. The mechanical fasteners by which the elements can be joined and separated easily without any breaking the joint are called temporary fasteners. The mechanical fasteners that can be separated only by breaking the joint between the mechanical devices are called the permanent fasteners. The bolts and pins are the example of temporary fasteners and rivets , welds are the example of permanent fasteners.

Complete step by step answer
The rivet is the mechanical fastener used for the permanent fastening. It consists of three parts. First is the head, second is the shank and third is the nail. There are many types of the rivets according to the shape of the head and size of the shank. The strength of the rivet depends on the material of the rivet, size of the shank and the atmospheric conditions in which the rivet is exposed. These are made of iron, steel and alloy metal. The types of the rivets are solid head rivet, snap head and countersunk head rivets.
The rivets are used for many types of the joints. Some of the important types of riveted joint are Lap joint, Butt joint and Diamond joint.

Note The rivet may fail due to shearing, tearing or compression. The size of the rivet for the joint is decided by the thickness of the plate. The efficiency of the riveted joint is compared with the strength of the solid plate.
