  • In any structure or assembly, certain whole-body motions and certain deformations are more common than others; the most likely (easiest to excite) motions will occur at certain natural frequencies. Certain exciting or forcing frequencies may coincide with the natural frequencies (resonance) and give relatively severe vibration responses. We will now discuss the much-simplified system shown in Fig.

  • This thesis aimed to apply the SEM for dynamic analysis of cracked beam subjected moving harmonic force in the frequency domain. Namely, the frequency response of a cracked beam subjected to moving harmonic force is obtained explicitly and examined in dependence upon the load and crack parameters. This task is acknowledged herein spectral analysis of cracked beam subjected to moving load.

  • With the advent of the atomic force microscope (AFM) came an extremely valuable analytical resource and technique, useful for the qualitative and quantitative surface analysis with sub-nanometer resolution. In addition, samples studied with an AFM do not require any special pretreatments that may alter or damage the sample, and permit a three dimensional investigation of the surface.

  • Raising the Bar for Safety: In response to the Deepwater Horizon oil spill in the Gulf of Mexico, the Obama Administration has launched the most aggressive and comprehensive reforms to offshore oil and gas regulation and oversight in U.S. history. The reforms, which strengthen requirements for everything from well design and workplace safety to corporate accountability, are helping to ensure that the U.S. can safely and responsibly expand development of its offshore energy resources.

  • Integrating statistics and dynamics within a single volume, the book will support the study of engineering mechanics throughout an undergraduate course. The theory of two- and three-dimensional dynamics of particles and rigid bodies, leading to Euler's equations, is developed. The vibration of one- and two-degree-of-freedom systems and an introduction to automatic control, now including frequency response methods, are covered.

  • Every organization—large and small—has managers. Someone must be responsible for formulating strategy, making plans, organizing resources, directing personnel, and controlling operations. This is true of the Bank of America , the Peace Corps , the University of Illinois , the Red Cross , and the Coca-Cola Corporation , as well as the local 7-Eleven convenience store. In this chapter, we will use a particular organization—Good Vibrations, Inc.—to illustrate the work of management.

  • Centerless grinding operations present some characteristic features that make the process especially susceptible to regenerative chatter instabilities. Theoretical study of these vibrations present some difficulties due to the large amount of parameters involved in the process and, in addition, such a study requires a precise determination of dynamic properties of the particular machine under study.
