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 […]
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 […]
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 […]
What is the difference between Heat and Temperature?
Have you ever thought that the heat and the temperature are the same? The answer is no. Heat and temperature are related to each other but are different concepts. In this article, we will understand how they are interconnected. Heat vs Temperature When two bodies of different temperatures bring them into contact with each other, […]
Universal Testing Machine – Construction and Working principle
The behaviour of the material can be tested by different testing methods, with the help of testing machines. The universal testing machine is a material testing machine used for static testing such as a tensile test or compressive test. It is also known as UTM. In this article, we have discussed the construction and the working principle […]
How the Impact Test is conducted?
In the previous tutorial, we have discussed the list of Material Testing Methods, and in this tutorial, we are going to discuss how to conduct the Impact Test. The behaviour of the material under dynamic loading is entirely different from the behaviour of the material under the static loading. The material may have high strengths but when it comes […]
What is Fatigue Failure in Material science?
Do you know what is Fatigue Failure? 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. Let’s discuss the Fatigue failure briefly. Fatigue Failure Fatigue Failure is defined as the brittle fractures that occurred while a repeated load […]
Stress Strain Curve | Stress Strain diagram
To study the behavior of any material which is subjected to a load, it is possible by relating the stress with strain while gradually increasing the load. the graph between the stress and strain is known as Stress strain Curve. Stress strain curve If we draw a graph between stress and strain while applying a […]
