This is the first mechanical engineering textbook that deals with the operational processes of systems: the analysis of their characteristics of motion. A system's motion often must comply with certain constraints, such as acceptable ranges of acceleration or deceleration. Determining the parameters of motion requires the composing and solving of differential equations that describe the system's operational processes. Calculus courses for mechanical engineering programs offer a method based on characteristic equations, which allows the solving of differential equations for one-degree-of-freedom systems. However, this method does not work for two-degree-of-freedom systems, such as shock absorbing mechanisms.This textbook presents the solutions for the entire spectrum of linear differential equations of motion for one- and two-degree-of-freedom systems. These solutions are obtained using the Laplace Transform methodology along with a newly presented table of 101 Laplace Transform pairs.

The academic course of Machine Design Elements and Assemblies (a.k.a. "Machine Design," "Mechanical Engineering Design," etc.) is based on the fundamentals of several different core disciplines, and should prepare students to meet challenges associated with solving real-life mechanical engineering design problems commonly found in industry. Other works focus primarily on verifying calculations of existing machine elements in isolation, while this textbook goes beyond and includes the design calculations necessary for determining the specifications of elements for new assemblies, and accounting for the interaction between them. Machine Design Elements and Assemblies addresses the design considerations associated with the functionality of a full assembly. Most chapters end with a design project that gets progressively more complex. Numerous reviews of prerequisite materials are purposely not included in this title, resulting in a more concise, more practical, and far less expensive product for students, engineers, and professors. Rounding out this incredible package are 120 problems and answers that can be assigned as homework. And nearly 400 additional problems are available on the book's affiliated website, www.machinedesignea.com.Michael Spektor holds a Ph.D. in mechanical engineering. His experience includes work in industry and academia in the former Soviet Union, Israel, and the U.S. He is also the author of Solving Engineering Problems in Dynamics, and Applied Dynamics in Engineering (Industrial Press, Inc.). Professor Spektor has taught courses in Material Science, Dynamics, Strength of Materials, and Machine Design. He was Chair of the Manufacturing & Mechanical Engineering Technology Department at Oregon Institute of Technology. He served as Program Director of the Manufacturing Engineering Bachelor degree completion program at Boeing, where he later developed a Master's Degree program.Chapter 1: Basics of Mechanical Engineering Calculations and Design.

This book is primarily a guide for professionals and can be used by students of Dynamics. It features 96 real-life problems in dynamics that are common in all engineering fields; including industrial, mechanical and electrical. And it uses a special table guide that allows the reader to find the solution to each specific problem. The descriptions of the solutions of problems are presented in the chapters 3 to 18. The analysis of the structure of the differential equation of motion, as well as the analysis of the components that constitute this equation presented in the Chapter 1 allow readers to understand the principles of composing the differential equation of motion for actual engineering systems. Presents the straightforward universal methodology of solving linear differential equations of motion based on the Laplace transform. The table of Laplace Transform pairs presented in the Chapter 1 is based on reviewing numerous related analytical sources and represents a comprehensive source containing sufficient information for solving the differential equations of motion for common engineering systems. Helps determine the number of possible common engineering problems based on the analysis of the structure of the differential equation of motion, as well as on the realistic resisting and active loading factors that constitute the differential equation of motion. Each paragraph represents a standalone description. There is no need to look for notations or analytical techniques throughout the book. The book contains all required supplemental information for solving the problems.

This new guide takes an analytical approach by using step-by-step universal methodologies to solve problems of motion in Mechanical and Industrial engineering. This is a very useful guide for students in Mechanical and Industrial Engineering, as well practitioners who need to analyze and solve a variety of problems in dynamics. It emphasizes the importance of linear differential equations of motion, using LaPlace Transform, in the process of investigating actual problems. It includes numerous examples for composing differential equations of motion.
