When a customer is looking for a product, they have no idea what they exactly want. Which means they do know what they want, but they fail to describe it in perfect context. So it is necessary to understand the customer needs to develop a product. This Kano Diagram model is helpful for the understanding […]
MECHANICAL ENGIEERING
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.
- Metrology
- Machine Design
- Production Technology
- Material science
- Strength of Materials
- Dynamics of Machinery

What is Technology S-Curve in Product Design?
In the course of Product Design and Development, the Technology S-Curve determines the performance in regards to time and effort. It assists in determining the level of maturity of the industry/product. Let us discuss more details on the Technology S-Curves. Technology S-Curve When evaluating a product or an industry, it is crucial to understand where […]
Technical Questioning and Mission Statement in Product Development
In the course of Product Development, the Technical questioning and the Mission statement are the two basic methods of weighing the two risks of the new product development. Those risks are Technical risk – can we make it? Market risk – will they buy it? The two simple tools to understand and clarify these risks […]
What are Product Development Planning Tools?
For any product development, Product Development planning is a necessary task for any kind of product. To perform this task, we have a different variety of tools. Such as Gantt Charts, PERT, CPM. Product development Planning Product Development planning Basic Constituents are What: Tasks When: Schedule Where: Equipment and facilities How: People, material, facility, and […]
Organizational structures in Product Development
Successful firms must organize their product development staff to implement the process in an effective manner. In this article, we will discuss the different organizational Structures used for product development and offer guidelines for choosing among these options. Organizational structures In general, Organizations Are Formed by Establishing Links among Individuals. A product development organization is […]
What is the Engineering Design Process?
In the course of Product Design and Development, The Engineering Design Process is the sequential design process that may involve multi-disciplines such as mechanical engineering, electrical engineering, architectural engineering, industrial engineering, material science, aerodynamics, fluid dynamics, and so on. Engineering Design Process As we have already mentioned that the Engineering Design Process is the sequential […]
What is the Myers-Briggs Type Indicator? | MBTI
Myers-Briggs Type Indicator, also known as MBTI is a simple measurement indicator of how people behave and contribute in work environment. It is a sort of a questionnaire kind of thing, that differs the psychological preferences of the people, how they perceive the world and make decisions. Myers-Briggs Type Indicator Originally, Isabel Myers and Katherine […]
What are Cam and Follower? What are the types?
You must have heard this Cam and follower mechanism is in Internal combustion engines. A Cam is a rotating machine element which gives reciprocating or oscillatory motions to another element known as the follower. Cam and Follower The Cam and the follower have a line contact and constitute a higher pair. Higher pair: When the […]
What is Torsionally Equivalent Shaft?
In General, shaft comprised of multiple cross-sectional diameters with different lengths. Some times it is necessary to assume the shaft as a uniform diameter and length for some calculations such as finding the natural frequency. In such cases, we have to replace the different cross-section diameters with the equivalent shaft of uniform diameter. Which will […]
Natural Frequency of Free Torsional Vibrations
In the previous articles, we have discussed how to find the Natural Frequency for Free Longitudinal Vibrations and for free Transverse Vibrations. In this article, we are going to discuss the Natural Frequency of Free Torsional Vibrations. As we know the natural Frequency of the Free Torsional Vibrations can be determined by the following methods. Equilibrium […]

What is Pickering Governor? How does it work?
The Pickering Governor is spring controlled load governor categorised under the centrifugal governors. We have discussed the Hartung Governor, Hartnell governor and Wilson-Hartnell Governor in the previous articles, which are also the spring-loaded governors with which have different construction and working principle from this type of governor. Pickering Governor Pickering Governor is spring-loaded governor as we have mentioned, instead […]
What is Wilson-Hartnell Governor? How does it work?
The Wilson-Hartnell Governor is spring controlled load governor categorised under the centrifugal governors. We have discussed the Hartung Governor and Hartnell governor in the previous articles, which are also the spring-loaded governors with which have different construction and working principle from this type of governor. Wilson-Hartnell Governor In this type of governor, there is no need for the […]
What is Hartung Governor? How does it work?
The Hartung Governor is spring controlled load governor categorised under the centrifugal governors. We have discussed the Hartnell governor in the previous article, which is also a spring-loaded governor which has a different working principle from this type of governor. Hartung Governor In this type of governor, there is no need for the load on […]
What is Hartnell Governor? How does it work?
In the previous articles, we have discussed the dead weight type governor such as the proter governor and the Proell governor.
