  • When man invented the wheel, he very quickly learned that if it wasn’t completely round and if it didn’t rotate evenly about it’s central axis, then he had a problem! The wheel would vibrate, causing damage to itself and it’s support mechanism and in severe cases, be unusable. As the task of manufacturing a replacement was so huge and time consuming, a method had to be found to minimize the problem. Research showed that the wheel and its shaft had to be in a state of balance, i.e.

  • Cân bằng tĩnh là cân bằng trên 1 mặt phẳng quay, có thể không cần đo pha, chỉ cần máy đo rung cầm tay là được. Khái niệm tĩnh ở đây không phải là đứng yên đâu, hồi trước người ta có làm như thế này: đặt trục lên 2 gối là 2 lưỡi dao để tìm vị trí nặng nhất. Nhưng bây giờ cho quay ở tốc độ cố định rồi đo, tính toán ra thôi. - Cân bằng động là cân bằng từ 2 mặt phẳng quay trở lên. Về lý thuyết tính toán thì dùng ma trận...

  • The article deals with a research on the design and manufacturing of a dynamic balancing machine, using dynamic load sensors and optical one, for calculating the unbalanced mass in thick rotating part on two choosen correction planes. Dynamic load sensors attached to the bearing supports of the machine help us determine the reaction forces generated by the unbalanced mass of the rotor. These load signals are filtered and digitized at a sampling rate which is synchronous to the rotor via an optical sensors.

  • Rawson and Tupper's Basic Ship Theory, first published in 1968, is widely known as the standard introductory text for naval architecture students, as well as being a useful reference for the more experienced designer. The fifth edition continues to provide a balance between theory and practice. Volume 2 expands on the material in Volume 1, covering the dynamics behaviour of marine vehicles, hydrodynamics, manoeuvrability and seakeeping. It concludes with some case studies of particular ship types and a discussion of maritime design.

  • When I decided to write this book, I was not fully aware of the reason why I was doing so. During the entire year spent in writing it, however, I had the opportunity to reflect upon its benefits for my professional maturity. First of all, this book has enabled me to write a sort of balance sheet of the first decade I have devoted to the study of corporate taxation. Quite surprisingly I have realized that there has been at least a minimum of coherence in my research.

  • Yet in recent years, ailing institutions have also made use of bad banks as a method for repairing the balance sheets without governmental interference. Between 2003 and 2005, Dresdner Bank transferred 35.5 billion euros in toxic loans and shares which had lost strategic relevance to a so-called Institutional Restructuring Unit (IRU). In 2008, WestLB, the Landesbank partially owned by the state of North Rhine-Westphalia, founded a consolidation vehicle named “Phoenix” in Dublin, Ireland.

  • Summary of Mechanics 0) The laws of mechanics apply to any collection of material or ‘body.’ This body could be the overall system of study or any part of it. In the equations below, the forces and moments are those that show on a free body diagram. Interacting bodies cause equal and opposite forces and moments on each other. Linear Momentum Balance (LMB)/Force Balance ˙ Equation of Motion Fi = L t2 t1 I) The total force on a body is equal to its rate of change of linear momentum. L Net impulse is equal to the change in momentum. When there is no...

  • In this book, the term Zen is used to roll together all of these con- cepts. This is not an orthodox treatment of Zen. The book could have been called the Yoga, Tao, or Way of Managing Projects. In the end all of these terms are pointing to the same basic strategy—regard every- thing as a part of a holistic, integrated system, set your intention to include all of your personal and nonpersonal goals, apply objectivity and subjectivity in dynamic balance, seek to perfect yourself and your performance while not being hung up about your imperfections, and recognize that a...

  • We think this book is unique in that it uses a novel and logical approach to present discussions of this topic from three general perspectives: scientific, social, and economic, and the integration within these important areas. We think this book is somewhat different than other environmental management books since we offer a more balanced view of the topic – many of the books available today concentrate primarily on just one of these three perspectives.

  • Targeting households and firms: influencing location choices. The demand side of balanced urban development involves measures to influence where households and firms choose to locate in an urban area. Although they are not yet well established, particularly in the developing countries, policies to influence location choices have led to some interesting experiments, including a “reverse” zoning scheme in the Netherlands (the “ABC” policy) and a mortgage instrument based on “location efficiency” in the United States.
