We have been discussed different Angular measuring Instruments so far. Sine Bar is the one of the precision Instrument among those. It will be used along with the Slip gauges in angle measurements. In this article, we are going to discuss the Construction, the working principle, Uses of Sinebar, Formula to determine the angle. Sine Bar Sine […]

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 […]
Working principle of Vernier Bevel Protractor
In Metrology, The angular measurements are frequently necessary for manufacturing industries. Vernier Bevel protractor is one of the angular measuring instrument used for close tolerances. 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 […]
