We have discussed what is a force in the previous article. let us discuss more details of force such as characteristics of Force, Representation of force, Classification of force, and Force System. Also, we will discuss how to draw the free-body diagrams and find the resultant force of a force system. Force is something that […]
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 […]
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 […]
What is the Fatigue Crack propagation rate?
Fatigue failure refers to the failure of the machine component due to repeated or cyclic loading. Due to the fluctuation in the stress, this failure occurs. This Fatigue Failure process starts with the Crack initiation due to the repeated cyclic loads. This crack propagates and leads to the Final fatigue failure. This Fatigue failure is […]
How to calculate Fatigue Life?
As we discussed earlier What is fatigue failure. Fatigue failure refers to the failure of the machine component due to repeated or cyclic loading. These cyclic or repeated loads are known as fatigue loads. Due to the fluctuation in the stress, this Fatigue failure occurs. Fatigue life means the number of cycles of stress that a component […]
Engineering Stress and Engineering Strain
In a Machine, every component is subjected to various forces. Due to these forces acting on the machine components, there are various types of stresses are induced. Where a simple stress is defined as the internal resistance force that opposes the external force per unit area. Where the Strain is defined as the deformation per unit […]
What is Creep and Stress Rupture Of Metals?
When a metal or an alloy is under a constant load or stress, it may undergo progressive plastic deformation over a period of time. This time-dependent strain is called creep. The Stress Rupture of Metals referred to the sudden and complete failure of a material under stress when there is a constant loading of the metals. Let us […]
How to calculate Fracture Toughness in metals?
In the previous article, we have discussed the different types of fracture. Ductile fracture and brittle fracture are the broad classifications of fractures. In this article, we will discuss how to calculate Fracture Toughness in metals to avoid failure. As we have discussed in the previous article, ductile fractures may occur in metals due to […]
