What do you mean by Applied Mathematics?

Applied mathematics involves the application of mathematics to problems that arise in various areas, e.g., science, engineering, or other diverse areas, and/or the development of new or improved methods to meet the challenges of new problems. We view applied math as the application of mathematics to real-world problems with the dual goal of explaining observed phenomena and predicting new, as yet unobserved, phenomena. Therefore, the emphasis is on both the mathematics, e.g. the development of new methods to meet the challenges of new problems, and the real world. The problems come from various applications, such as physical and biological sciences, engineering, and social sciences. Their solutions require knowledge of various branches of mathematics, such as analysis, differential equations, and stochastics, utilizing analytical and numerical methods. Very often our faculty members and students interact directly with experimentalists to see their research results come to life

Who Should Study Thermodynamics?

Thermodynamics has a few fundamental laws and principles. These laws can be applied to a wide range of problems. Thermodynamics is core to all branches of engineering and allows an understanding of the mechanism of energy conversion. It is next to impossible to identify any area where there is no interaction in terms of energy and matter. It is a science having its relevance in every occupation. Scientists are interested in gaining a fundamental understanding of the physical and chemical behavior of fixed quantities of matter at rest. They use the principles of thermodynamics to relate the properties of matter. On the other hand, engineers are generally interested in studying the systems and their interaction with their surroundings.

What are the functions of Cutting Fluids in the Machining Process?

The important functions of cutting fluids are given as under. (i) Cutting fluid washes away the chips and hence keeps the cutting region free. (ii) It helps in keeping freshly machined surface bright by giving a protective coating against atmospheric, oxygen and thus protects the finished surface from corrosion. (iii) It decreases the wear and tear of the cutting tool and hence increases tool life. (iv) It improves machinability and reduces power requirements (v) It prevents expansion of workpieces. (vi) It cools the tool and workpiece and removes the generated heat from the cutting zone. (vii) It decreases adhesion between chip and tool; provides lower friction and wear, and a smaller built-up edge.
