Mechanical Vibrations: A Lecturebook introduces the analysis of mechanical vibration systems by progressing from the fundamental equations of motion for discrete systems to the study of free and forced vibration responses in both discrete and continuous systems. It also covers practical applications and approximate solution methods used in vibration analysis. The appendices provide supporting material in calculus, complex numbers, relevant mathematical functions, dynamics, linear algebra, operator self-adjointness, a proof related to Lagrange’s equations, and transmissibility ratios.

CHARLES M
KROUSGRILL
Charles M. Krousgrill: Charles M. Krousgrill is a Professor in the School of Mechanical Engineer-ing at Purdue University. He received his M.S. in mechanical engineering from Purdue University in 1975, and his M.S. and Ph.D. in applied mechanics from the California Institute of Technology in 1976 and 1980, respectively. During his more than 30 years at Purdue University, few, if any, individuals have had a greater impact on the university’s undergraduate students and the institu-tion’s commitment to engineering education. Dr. Krousgrill’s efforts in this regard have garnered numerous awards and international accolades. To date, these include the Purdue University School of Mechanical Engineering’s Harry L. Solberg Best Teacher Award (eight times), the Purdue Uni-versity College of Engineering’s Potter Best Teacher Award (four times), the Purdue University Murphy Best Teacher Award, the 2010 Purdue University Helping Students Learn Award, the 2010 Purdue Alumni Association Special Boilermaker Award and the American Society of Engineering Education’s 2011 Archie Higdon Distinguished Educator Award – the de facto lifetime achieve-ment award for educational accomplishments in the field of mechanics. In January 2018, it was announced that Dr. Krousgrill had been awarded the named 150th Anniversary Professorship by Purdue University. Outside of the classroom, Dr. Krousgrill conducts research in the general areas of dynamics and mechanical vibration.
