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.

Major axis AB & minor axis CD are 100 mm and 70 mm long respectively. Draw half ellipse by arcs of circles Method and another half by Rectangle Method. OR Draw an Involute of a circle with diameter 50 mm. String length is equal to the circumference of circle. OR Construct a…
Construction of Spiral Curves/सर्पिल वक्रों का निर्माण If a line rotates in a plane about one of its ends and if at the same time, a point moves along the line continuously in one direction, the curve traced out by the moving point is called a spiral.The point about which the line…
Construction of Involute Curves The involute is a curve traced out by an end of a piece of thread unwound from a circle or a polygon, the thread being kept tight. It may also be defined as a curve traced out by a point in a straight line which rolls without slipping…
Construction of Cycloidal Curves - Cycloid, Epicycloid and Hypocycloid/साइक्लोइडल कर्व्स का निर्माण - साइक्लोइड, एपिसाइक्लॉइड और हाइपोसाइक्लॉइड These curves are generated by a fixed point on the circumference of a circle, which rolls without slipping along a fixed straight line or a circle. The rolling circle is called generating circle and the…
Conic sections are obtained by cutting off a right circular cone by section planes at varying angles relative to its axis. Conic sections include the circle, ellipse, parabola, and hyperbola. शंकु वर्गों को इसकी धुरी के सापेक्ष अलग -अलग कोणों पर अनुभाग विमानों द्वारा एक सही गोलाकार शंकु को काटकर प्राप्त किया जाता है। शंकु वर्गों में सर्कल, दीर्घवृत्त, परबोला और हाइपरबोला शामिल हैं।
Engineering Drawing Instruments are essential to engineering and building projects drawings. Drawing enhances inventiveness and fosters the creation of new inventions. Before construction, a thorough analysis of the structure can be done utilising drawings. There are some engineering sketching programmes that are more accurate. But there are still few places and little constructions where drawing on paper is employed. Various drawing instruments are used to create drawing on sheet or paper. This post gives details of the instruments used in engineering drawing.
