Design Data Handbook: The Essential Book for Mechanical Engineers by K. Mahadevan and B. K. Balaveera Reddy

Design Data Handbook by K. Mahadevan: A Comprehensive Guide for Mechanical Engineers

Machine design is one of the important subjects in mechanical engineering and a thorough knowledge of the design aspects of machine elements is essential for all design engineers. Working out the design of a machine as a whole, or its components, usually involves the use of several formulae, graphs, standard tables and other relevant data. Availability of all such information in one handbook not only eliminates the unnecessary task of remembering the required formulae and equations, but also helps design engineers to solve the problems in machine design quickly and efficiently.

One such handbook that has been widely used by mechanical engineers for decades is Design Data Handbook by K. Mahadevan. This handbook has been compiled by K. Mahadevan, former principal of Karnataka Regional Engineering College (NIT-K), Surathkal, Karnataka, and K. Balaveera Reddy, former vice chancellor of Visvesvaraya Technological University, Belgaum, Karnataka, and professor of mechanical engineering at NIT-K. The handbook has been published by CBS Publishers & Distributors Pvt Ltd and is currently in its fourth edition.

In this article, we will explore what is Design Data Handbook, why it is useful for mechanical engineers, what are its main features, how to download it for free, how to use it effectively, and what are the legal and ethical issues of downloading it for free.

What is Design Data Handbook?

Design Data Handbook is a comprehensive reference book that contains design data for various machine elements such as gears, shafts, bearings, springs, belts, chains, clutches, brakes, screws, bolts, nuts, welds, rivets, keys, couplings, pipes, flanges, valves, nozzles, pumps, compressors, turbines, engines, boilers, heat exchangers and more. The design data includes dimensions, specifications, standards, formulae, graphs, tables and charts that are useful for designing and selecting these machine elements.

The handbook also covers some basic topics such as units and conversions, material properties, stress analysis, failure theories, fatigue, creep, fracture mechanics, vibration, lubrication, tribology, thermodynamics, fluid mechanics, heat transfer, refrigeration and air conditioning that are essential for understanding the design principles and applications.

The handbook is divided into 18 chapters and each chapter covers a specific topic or machine element. The chapters are arranged in a logical sequence that follows the typical design process from problem definition to solution verification. The chapters are as follows:

• Introduction

• Units and Conversions

• Material Properties

• Stress Analysis

• Gears

• Shafts

• Bearings

• Springs

• Belts and Chains

• Clutches and Brakes

• Screws, Bolts, Nuts and Welds

• Rivets, Keys and Couplings

• Pipes, Flanges, Valves and Nozzles

• Pumps, Compressors and Turbines

• Engines, Boilers and Heat Exchangers

• Refrigeration and Air Conditioning

• Vibration and Balancing

• Lubrication and Tribology

• It helps to design and select machine elements based on the required specifications, standards, performance, safety and reliability criteria.

• It helps to verify and validate the design solutions by providing graphs, tables and charts that show the variation of design parameters with respect to different factors.

• It helps to enhance the knowledge and skills of mechanical engineers by providing clear explanations, examples, illustrations and references for each topic or machine element.

• It helps to prepare for competitive exams, interviews, projects and presentations by providing a quick and easy access to the relevant design data.

What are the main features of Design Data Handbook?

Design Data Handbook has many features that make it a valuable resource for mechanical engineers. Some of them are:

• It is written in a simple and concise language that is easy to understand and follow.

• It is organized in a logical and systematic manner that follows the typical design process from problem definition to solution verification.

• It covers a wide range of topics and machine elements that are relevant for mechanical engineering.

• It provides design data in SI and metric units that are widely used in engineering practice.

• It provides design data in both numerical and graphical forms that are convenient for calculation and visualization.

• It provides design data based on the latest standards, codes, specifications and recommendations from various national and international organizations such as ISO, DIN, BIS, ASME, ANSI, SAE, AGMA, API, etc.

• It provides design data based on the latest research and development in the field of mechanical engineering.

• It provides clear explanations, examples, illustrations and references for each topic or machine element.

• It provides cross-references between different chapters and topics for easy navigation and comparison.

• It provides appendices that contain additional information such as conversion factors, abbreviations, symbols, glossary, index, etc.
