Metrology Basic Topics list
Metrology is a science of measurement. It meant to understand the units of each quantity and the realisation of the units and calibration. In each country, they follow different unit systems, among them, the Metric system is the predominant system in the world. In this article, we have listed all the different Metrology topics that we have […]
What is the Universal Bevel Protractor?
Vernier Bevel Protractor is often known as the Universal Bevel Protractor. It is one of the angular measuring instrument used for close tolerances within 5 minutes. We have already discussed the Vernier Bevel protracter in previous articles. But again we just rewrote everything here instead of redirecting you to that article. Still, you can check that article […]
Working Principle of Optical Bevel Protractor
Optical Bevel Protractor is the development of the Vernier Bevel Protractor which has the ability to measure the angles up to 2 minutes. But in vernier Bevel protractor it is 5 minutes. In this article, we are going to discuss the Construction and the working principle of the Optical Bevel Protractor. Optical Bevel Protractor Optical […]

We are going to discuss the construction and the working principle of the Vernier Bevel protractor in this article. Vernier Bevel Protractor Bevel Protractors are the Angular measuring devices. Vernier Bevel […]
What are Angular Measuring Instruments?
The angle is a measurement that we can measure between the two lines which meet at one point. Angular measurements are playing a very crucial role in measurements. The best example is that the Ships and the Aeroplanes will navigate with the help of The precise angular directions of the landing area. Let’s discuss Angular […]
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?
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 […]
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 […]
What are the Principal Stresses and Principal Planes?
From all the way, we have discussed the different types of stress and strains, Now its time to understand what are the principal stresses. The maximum stress induced in a plane is called the principal stress and the plane at which the maximum stress induced referred to the principal plane where the shear stress is […]
Crane Hook Design Problem sample
Crane Hook Design Problem: The crane hook carries a load of 20 kN as shown in given below Fig. The section at X-X is rectangular whose horizontal side is 100 mm. Find the stresses in the inner and outer fibres, the given section. Solution: Given data (All are in Metric Units) Load (W) = 20kN […]
What are the different commonly used cross-section properties ?
When we say common Cross-section properties, what we will think of? First of all Sectional area, Section modulus, the moment of inertia, and few other. The different cross-section properties for the different cross-sections such as circular, square, rectangular and trapezoidal and triangular are discussed briefly in this article. First of all, we have to understand […]
What are the different Non-Metallic Materials?
In material science, materials are classified into four groups Metals, Non-metals, Ceramics, Composites. In this article, we are going to discuss Non-Metallic Materials. The Non-Metallic materials are used in engineering due to their less density and flexibility, resistance to electricity, heat and most importantly it is available at low costs. Non-Metallic Materials Before going into the topic it […]
What are the different Non-Ferrous Metals?
The metal which is consisting of the main constituent other than the iron is known as Non-ferrous metals. For example aluminium, copper, lead, nickel, tin, titanium and zinc. We have discussed the characteristics of the different Non-ferrous metals and the purpose and use of the non-ferrous metal in different applications in this article. Non-Ferrous Metals Having lightweight, high conductivity, corrosion resistance […]
What are the different Case Hardening processes?
Case Hardening is also known as Surface Hardening. Sometimes also are known as the Face Hardening. The process of hardening the surface of the components is known as the Case Hardening. There are different types of Case hardening processes available. We have discussed each of them here! Case Hardening / Surface Hardening The process of Hardening […]
What are the different Heat Treatment processes?
In material science, the Heat treatment processes used to impart the physical properties by altering the microstructure.
