Riveted Joint: Lozenge Joint Riveted Joint for Structural Use–Joints of Uniform Strength (Lozenge Joint) A riveted joint known as Lozenge joint is used for roof, bridge work or girders etc. In such a joint, diamond riveting is employed so that the joint is made of uniform strength.  b =Width of the…
Riveted Joint: Introduction, Classification, Strength and Efficiency of Riveted Joint Riveted Joint is a Permanent Joint? Mechanical joints are broadly classified into two classes, viz., Non-permanent joints and permanent joints. Non-permanent joints can be assembled and disassembled without damaging the components. Examples of such joints are threaded fasteners (like screw-joints), keys, couplings,…
A knuckle joint is a hinged joint that connects two rods, typically a ball and socket joint. Knuckle joints are used to link two rods that require flexibility or angular movement.
Cotter joints are used to connect two rods, subjected to tensile or compressive forces along their axes. These joints are not suitable where the members are under rotation.
Basic Mechanical Properties of Engineering MaterialsIntroduction to Mechanical PropertiesMaterials are defined by their qualities. They could be hard, ductile, or hefty. Alternatively, they can be soft, fragile, or lightweight. Mechanical properties define how materials behave under external forces. They often refer to the elastic and plastic properties of a material. Material selection…
Simple stresses encompass a range of fundamental mechanical phenomena, including tension, compression, shear, bearing, and torsion. Each type of stress manifests uniquely in different components and structures, influencing their behavior and performance under various conditions.
Introduction to Machine Design: Machine design is a problem-solving technique with the help of existing scientific principles in an iterative manner.

This section describes in brief about the different engineering materials and their classifications used for design of various components.
Factor of Safety in Machine Design and Drawing What is Factor of Safety ? Factor of safety is defined as the "ratio of critical load to safe load". When related to stresses it is defined as the "ratio of Ultimate stress to design stress". The factor of safety provides the margin by which there…
Preferred Series Numbers in Machine Design and Drawing What is Preferred Series Numbers? The Preferred Series Number is a designed machine component that needs standardization to avoid variations. It implies that the product's important parameters should be common in nature. For example, the sizes of the ingots (Raw Material) available in the…
