Section Modulus is also referred to as the Polar Modulus or the Torsional Sectional Modulus. It is denoted by Zp. Along with these, there are two more definitions also there to discuss. So let’s discuss this topic in more detail. (FYI: We discuss this topic more in terms of circular shafts, If you are looking […]
In Mechanical Engineering, Machine Design is subjected to creating new or Advanced machines. This involves improving the existing machines to better machines.
The design process is a time-consuming process which includes implementing an Idea and considering the commercial and economic aspects, Making the idea into a shape in the form of drawings by keeping the available resources in mind to make the actual Idea into a life.
This is the art of Mechanical engineering.
The Idea Thake shape and eventually come to life

What is a shafts misalignment? |Causes|Effects|
When two equipment (Driver and driven) need to coupled together, then they need to be aligned properly to couple together. Installing the two equipment with 100% alignments is not possible. These misalignments can be accommodated by the special member called coupling. There are two different types of couplings. Flexible couplings and rigid couplings. These coupling […]
What are the different Flexible coupling types?
In the previous article, we have discussed the Functional requirement of coupling, coupling classification and Rigid Coupling types. In this article, we are going to discuss the different Flexible coupling types. Flexible coupling types Flexible couplings are used to connect two shafts having axial, radial and angular misalignment. Following are the different types of flexible couplings. […]
What is Shaft coupling? Different types of Coupling?
A shaft coupling is a mechanical element that connects the two shafts together to transmit the torque from one end to the other by accommodating the misalignment. Usually of a shaft can be made up of limited lengths so we have to make a couple multiple pieces of shafts to achieve the larger lengths to […]
How Vicker’s Hardness Test is conducted?
The ability of a material to resist indentation or penetration is called Hardness. To test the hardness of any material is simply forcing an indentor into the surface of the metal by applying the load. There are different methods are developed to test this hardness. In the previous article we have discussed The Brinell Hardness test, the Rockwell Hardness […]
How Rockwell Hardness Test is conducted?
The ability of a material to resist indentation or penetration is called Hardness. To test the hardness of any material is simply forcing an indentor into the surface of the metal by applying the load. There are different methods are developed to test this hardness. In the previous article we have discussed The Brinell Hardness test, this article, […]
How Brinell Hardness Test is conducted?
The ability of a material to resist indentation or penetration is called Hardness. To test the hardness of any material is simply forcing an indentor into the surface of the metal by applying the load. There are different methods are developed to test this hardness. In this article, we are going to discuss one of the […]
What are the Non-Destructive testing methods?
The components that we design and engineering should satisfy the service and the requirement. For that, engineers make sure that the finished product should be tested before it is going to be installed and start functioning. Engineers employed few testing methods both destructive and the non-destructive tests of the materials. Let’s discuss what are the […]
Shear Force and bending moment diagram for Simply supported Beam
In the previous Article, we have discussed the Shear Force and bending moment diagram for Cantilever Beam. In this article, we are going to discuss the Shear Force and bending moment diagram for Simply Supported Beam. Shear force and Bending moment diagram in beams can be useful to determine the maximum absolute value of the shear force and […]
How Compression Test is conducted?
In the previous tutorial, we have discussed the list of Material Testing Methods, and how to conduct the Tensile test, in this tutorial we are going to discuss how to conduct the Compression test. Compression Test The Compression test is also similar to the tensile test, the way we conduct it on the UTM. It also comes under the destructive […]
How Tensile Test is conducted?
In the previous tutorial, we have discussed the list of Material Testing Methods, in this tutorial we are going to discuss how to conduct the tensile test. Tensile Test The tensile test comes under the destructive test where we apply the gradually increased load up to the material get fracture. So a tensile test is a static […]
What are the different Material Testing Methods? (Testing of Materials)
The components that we design and engineering should satisfy the service and the requirement. For that, engineers make sure that each type of material should be tested before we used for the making of the components. Along with the strength, there are other properties are also needs to test such as hardness, toughness, brittleness, etc. […]
Design of Key for shaft in Machine Design
In the Previous article, we have discussed different types of keys for shafts, Now we are going to discuss what are the different types of forces acting on Key, and the design of Key for the shaft. Different forces acting on the Keys First of all, we have to know what are the different types of […]
What are the different types of Keys in machine design?
In mechanical engineering, Key is a part of a machine or equipment where it is used to connect the rotating machine element to the shaft and enables the torque transmission. In this article, we are going to discuss what are the different types of Keys in machine design. What is a Key? As we said above […]
What is Notch Sensitivity?
What exactly the notch sensitivity means? From our previous article, we have discussed how a fillet or a notch or a hole can reduce the stress concentration. But in this case, it will look somewhat different. actually, due to the presence of the notch or a hole in the body, the body tends to have […]
What are the Methods of Reducing Stress Concentration?
We have discussed how the stress concentration effect the different cross-section mechanical components. Due to the irregular stress distribution, stress concentration increases and let the component failure. So how we can reduce the stress concentration? There are few methods of reducing stress concentration. Methods of reducing stress concentration Before getting into the topic we have to […]
What is Stress Concentration? How to reduce it?
We have been seeing the shafts with the different cross-sections. What would really happen when a mechanical component has a different cross-section? Would it affect the stress distribution in the component? Yes exactly. Let’s see how the irregular stress distribution results in stress concentration. Stress Concentration Stress concentration occurs due to the irregular stress distribution. This irregular stress […]
Difference between Fatigue Limit and Endurance Limit
As we discussed earlier What is fatigue failure. The Fatigue refers to the failure of the machine component due to the repeated or cyclic loading. Whereas the fatigue strength or fatigue limit or Endurance limit is used to describe the material property that the cyclic load can be applied to the material without causing the failure. […]
What is Fatigue failure in material science?
In Strength of materials, Fatigue refers to the failure of the machine component due to the repeated or cyclic loading. Due to the fluctuation in the stress, this failure occurs. Let’s discuss the Fatigue failure in briefly. Fatigue Failure Fatigue failure is defined as the brittle fractures occurred while a repeated load or cyclic load […]
What are the various Theories of Failure under static load?
Prediction of the failure of the machine component in the case of the uniaxial stresses(Simple tension or compression) is very simple by understanding the Stress-strain curve. Predicting the failure of any machine component is complicated when the machine component is subjected to the different types of Bi-axial stresses(Component subjected to two different stresses) or Tri-axial […]
