In Metrology The least count of an instrument is the smallest change in the value that can be measured with the measuring instrument. Least count for Steel Ruler For example in a Steel Ruler, there are twenty divisions between each 10-millimetre scale reading. So the least count for this steel ruler is 0.5 millimetre. The formula for […]
Mechanical Engineering is the discipline that applies engineering, physics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines.
Understanding of Mechanical engineering involves core areas including the Mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity.
In this Edublog, we help you understand the Basic engineering concepts, the engineering principles, definitions, laws, derivations and functionalities of machines in the following subjects with the help of concise articles, tutorials and step by step guides prepared by the Senior engineering Experts for free.
- Machine Design
- Production Technology
- Material science
- Strength of Materials
- Dynamics of Machinery
- Engineering Mechanics

In metrology, Vernier calliper is a precision measuring device used to measure the dimensions of the workpiece with high accuracy and precision. The construction and working principle of vernier caliper is explained in the previous article (Click here). In this article, we are going to discuss the different Vernier Caliper types. Vernier Caliper Types According to […]
In Metrology, the Surface gauge is a non-precision instrument, Used to draw the parallel lines and to find the centre of round section material. Simply it is used to scribe parallel lines on the workpiece. Why do we need to draw parallel lines or finding the centre of the cylindrical object? the answer is to set the Tool and […]
Topic: Measurement systems | System of Measurements The basic fundamental Units in the system of measurements are Length, Time, Mass, Temperature etc. All the physical quantities can be expressed in terms of these fundamental units. The Different system of measurements can be used in different countries are discussed in the following video. If you like to read the […]
Metrology is a science of measurements. We have discussed what are the different Linear measuring instruments. Vernier scale is a precise measuring instrument, Comparatively low accuracy than the other precision measuring instruments. The different types of Vernier callipers are available to measure internal, external measurements. In this article, we are going to discuss the Vernier Calliper Diagram, […]
