Abstract Since the discovery of the computer, it has taken over the world. It’s almost like the industrial revolution or even better than that. Every business sector has taken it into their system which has resulted […]
Secret Communication System Using Multi-Image Steganography For Military Application
A Final year project on “Secret Communication System Using Multi-Image Steganography For Military Application” was submitted by Pratik Bhagwandas Wani (from JSPM’S Rajarshi Shahu College Of Engineering) to extrudesign.com. Abstract Information security plays an important role when considering data transmission. Generally, we use cryptography for information hiding and sending secret messages in the form of text. Nowadays, there […]
How to calculate the force required to lift the load with Pulley?
Lifting a load with a pulley seems simple and effortless but, have you ever wondered how much effort is required to lift a certain amount of load with a pulley or system of pulleys? Let us understand the different systems of pulley arrangments and see how we can calculate the force required to lift the […]
How to Calculate Centroid and Centre of Gravity?
Do you know the difference between the Centroid and Centre Of Gravity? In simple words, the Centroid is the geometrical centre of the body, whereas the centre of gravity is the point where the total weight of the body focuses upon. Let us see How we can Calculate the Centroid and Centre Of Gravity for […]
How to calculate the Coefficient of Friction?
Do you know what is Friction? When a body moves or tends to move over another body, a force opposing the motion develops at the contact surfaces. The force which opposes the movement or the tendency of movement is called the frictional force or simply friction. We feel the contacting surfaces to be smooth. Actually, […]
How to calculate all forces in Truss with Methods of Section?
A truss is a structure made up of slender members or beams pin-connected at ends and is capable of taking loads at joints. Truss is a rigid structure. They are used as roof trusses to support sloping roofs and as bridge trusses to support the deck. In many machines, steel trusses are used. Transmission towers […]

How to calculate Corrosion Rate?
The study of the corrosion of metals has been centered on equilibrium conditions and the tendency of metals to corrode, which has been related to the standard electrode potentials of metals. However, corroding systems are not at equilibrium, and thus thermodynamic potentials do not tell us about the rates of corrosion reactions. The kinetics of […]
What is Precipitation Strengthening/Hardening?
Precipitation Strengthening/Hardening is a heat treatment technique used to increase the yield strength of many metal alloys. Especially the malleable metals such as the alloys of aluminum, magnesium, nickel, titanium, and some steels and stainless steels. Precipitation hardening is also called age hardening or particle hardening. Let us discuss more details about What is Precipitation […]
How to calculate Hoop Stresses?
In the previous article, we have discussed stresses in a thin cylinder, we have discussed that the wall of the cylindrical shell subjected to internal pressure due to the fluid has to withstand two types of tensile stresses. Those are Circumferential stress or hoop stress and longitudinal stress. In this article let us see how we […]
Production of Copper and Copper Alloys
Copper is one of the few metals that can occur in nature in a directly usable metallic form. Copper is a pinkish-orange color metal that is very soft, malleable, and ductile metal with very good thermal and electrical conductivity. The copper (Cu) atomic number is 29 from the periodic table. Let us discuss more details […]
Production of Aluminum and Aluminum Alloys
Aluminum is a silvery-white lightweight metal of main group 13 from the periodic table. It is the most widely used non-ferrous metal. Let us discuss the engineering properties, production, and different alloys of aluminum. Engineering Properties of Aluminum Aluminum possesses a combination of properties that make it an extremely useful engineering material. Aluminum has a […]
Stabilization Of Clay Soil Using Coir Fibre And Calcium Bentonite
A Final year project on “Stabilization Of Clay Soil Using Coir Fibre And Calcium Bentonite” was submitted by Ajay Kumar (from Sri Sairam engineering college Chennai) to extrudesign.com. ABSTRACT Soil is a natural resource. Some waste materials such as calcium bentonite, coir fiber may use to make the soil to be stable. The addition of such materials will […]
What are Alloy Steels?
Alloy steels are developed to overcome the Plain carbon steel limitations and deficiencies. Alloy steels, in general, cost more than plain-carbon steels, but for many applications, they are the only materials that can be used to meet engineering requirements. Let us discuss the alloy steels in detail. As we mentioned that alloy steels are developed […]
How to calculate Miller Indices for Crystallographic planes?
Sometimes it is necessary to refer to specific lattice planes of atoms within a crystal structure, or it may be of interest to know the crystallographic orientation of a plane or group of planes in a crystal lattice. To identify crystal planes in cubic crystal structures or hexagonal structures, the Miller notation system is used. […]
Production of Iron And Steel
Metals and alloys have many useful engineering properties and so have a widespread application in engineering designs. Iron and its alloys (principally steel) account for about 90% of the world’s production of metals, mainly because of their combination of good strength, toughness, and ductility at a relatively low cost. Each metal has special properties for […]
Principal Metallic Crystal Structures BCC, FCC, and HCP
Most elemental metals about 90% crystallize upon solidification into three densely packed crystal structures. Those are body-centered cubic (BCC), face-centered cubic (FCC), and hexagonal close-packed (HCP). Let us discuss these Principal Metallic Crystal Structures in detail. Important Definitions👉 Crystal: is a solid composed of atoms, ions, or molecules arranged in a pattern that is repetitive […]
