This book was released on 2019-04-15 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2018 in the subject Engineering - Mechanical Engineering, Junagadh Agricultural University (College of Agril Engineering & Technology), course: M.Tech Thesis, language: English, abstract: The objectives of this study are to develop a mini tractor mounted clod crusher, to evaluate the performance of the developed machine and to work out economics of the machine. In tillage tools used in India faces problem like, poor soil-tire interface, clod formation, compaction due to heavy traffic and timeliness in operation. Hence, it was planned to fabricate three different types of clod crusher and to evaluate its performance with clod crusher implements. To achieve this objective a prototype implement consisting of three different types of clod crusher cylinders’ like as square spike, round spike and spiral arrangement of spike were developed costing Rs. 7000/- per each cylinder. The newly developed implement was tested in field condition to evaluate its performance. Their performance results were analyzed in terms of tilling quality of soil and machine parameters. The effects of treatments on soil physical properties like soil bulk density, clod MWD were evaluated. Machine performance parameters like fuel consumption, field efficiency and cost of operation were also studied. Better performance in terms of tilling quality of soil was obtained using clod crusher (square spike) attachment to cultivator. The optimum values of clod MWD, clod crushing field efficiency and fuel consumption were found 13.64 mm, 78.37 % and 7.02 lit/ha respectively. The operating cost were found 882, 1050 and 988 ₹/ha in square spike, round spike and spiral arrangement respectively. Using clod crusher attachment to cultivator a farmer can save more rupees against another implement which is used for seed bed preparation.

Download or read book Introduction to Agricultural Engineering written by Harry L. Field and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for use in introductory courses in colleges of agriculture and in other applications requiring a problematic approach to agriculture. It is intended as a replacement for an Introduction to Agricultural Engineering by Roth, Crow, and Mahoney. Parts of the previous book have been revised and included, but some sections have been removed and new ones has been expanded to include a chapter added. Problem solving on techniques, and suggestions are incorporated throughout the example problems. The topics and treatment were selected for three reasons: (1) to acquaint students with a wide range of applications of engineering principles to agriculture, (2) to present a selection of independent but related, topics, and (3) to develop and enhance the problem solving ability of the students. Each chapter contains educational objectives, introductory material, example problems (where appropriate), and sample problems, with answers, that can be used for self-assessment. Most chapters are self-contained and can be used independently of the others. Those that are sequential are organiZed in a logical order to ensure that the knowledge and skills needed are presented in a previous chapter. As principal author I wish to express my gratitude to Dr. Lawrence O. Roth for his contributions of subject matter and gUidance. I also wish to thank Professor Earl E. Baugher for his expertise as technical editor, and my wife Marsha for her help and patience. HARRY FIELD v 1 Problem Solving OBJECTIVES 1. Be able to define problem solving.

Book excerpt: After giving a brief history of tillage practices and implements used throughout the world dating back to ancient times, this book goes on to describe the basic soil mechanics techniques needed to calculate the forces developed in soil by simple-shaped cutting tools. The methods of measuring soil mechanical properties, water pressure in soil and shear rate effects are touched upon. A review is given of two and three dimensional soil cutting mathematical mechanics models to predict soil cutting forces and soil volumes disturbed by cutting and tillage tools, as well as the state-of-the-art of soil loosening, structural rearrangement and plant growth as affected by tillage tools. The author also includes an introduction to the analysis of traction machines. There are many numerical examples of mechanical analyses and predictions worked out in the various sections of the book as well as numerous unsolved problems at the end of a number of the chapters.Written in a textbook style, this monograph is ideal for anyone wanting to learn modern techniques for the mechanical description of soil cutting and tillage forces and soil volumes disturbed. It also provides a reference for analytical formulae and calculated force forces. It will be of interest to universities and colleges worldwide which have Agricultural Engineering Programs, Civil and Mechanical Engineering schools which specialize in soil mechanics and construction machinery as well as to research stations worldwide with interests in soil tillage, soil physics etc.

Download or read book Fundamentals of Tractor Design written by Karl Theodor Renius and published by Springer Nature. This book was released on 2019-10-28 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook offers a comprehensive review of tractor design fundamentals. Discussing more than hundred problems and including about six hundred international references, it offers a unique resource to advanced undergraduate and graduate students, researchers and also practical engineers, managers, test engineers, consultants and even old-timer fans. Tractors are the most important pieces of agricultural mechanization, hence a key factor of feeding the world. In order to address the educational needs of both less and more developed countries, the author included fundamentals of simple but proved designs for tractors with moderate technical levels, along with extensive information concerning modern, premium tractors. The broad technical content has been structured according to five technology levels, addressing all components. Relevant ISO standards are considered in all chapters. The book covers historical highlights, tractor project management (including cost management), traction mechanics, tires (including inflation control), belt ground drives, and ride dynamics. Further topics are: chassis design, diesel engines (with emission limits and installation instructions), all important types of transmissions, topics in machine element design, and human factors (health, safety, comfort). Moreover, the content covers tractor-implement management systems, in particular ISOBUS automation and hydraulic systems. Cumulative damage fundamentals and tractor load spectra are described and implemented for dimensioning and design verification. Fundamentals of energy efficiency are discussed for single tractor components and solutions to reduce the tractor CO2 footprint are suggested.

Download or read book ANOVA and ANCOVA written by Andrew Rutherford and published by John Wiley & Sons. This book was released on 2011-10-25 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides an in-depth treatment of ANOVA and ANCOVA techniques from a linear model perspective ANOVA and ANCOVA: A GLM Approach provides a contemporary look at the general linear model (GLM) approach to the analysis of variance (ANOVA) of one- and two-factor psychological experiments. With its organized and comprehensive presentation, the book successfully guides readers through conventional statistical concepts and how to interpret them in GLM terms, treating the main single- and multi-factor designs as they relate to ANOVA and ANCOVA. The book begins with a brief history of the separate development of ANOVA and regression analyses, and then goes on to demonstrate how both analyses are incorporated into the understanding of GLMs. This new edition now explains specific and multiple comparisons of experimental conditions before and after the Omnibus ANOVA, and describes the estimation of effect sizes and power analyses leading to the determination of appropriate sample sizes for experiments to be conducted. Topics that have been expanded upon and added include: Discussion of optimal experimental designs Different approaches to carrying out the simple effect analyses and pairwise comparisons with a focus on related and repeated measure analyses The issue of inflated Type 1 error due to multiple hypotheses testing Worked examples of Shaffer's R test, which accommodates logical relations amongst hypotheses ANOVA and ANCOVA: A GLM Approach, Second Edition is an excellent book for courses on linear modeling at the graduate level. It is also a suitable reference for researchers and practitioners in the fields of psychology and the biomedical and social sciences.
