This Third Edition of the well-received engineering text retains the clarity of exposition that made the previous editions so popular, and contains the most widely-used problem sets in the business. Approach to vibration analysis is clear, concise, and simple, backed up by a wealth of problems and examples. Multi-degree-of-freedom problems are well-prefaced with two-degree-of-freedom cases. There is a special treatment of damping, including non-viscous problems (standard texts make much use of viscous damping, but most practical examples are not viscous). Now includes an excellent development of Rayleigh's principle and an introduction to finite element vibration analysis. Contains 100 new problems.Steidel, Robert F. is the author of 'Introduction to Mechanical Vibrations', published 1989 under ISBN 9780471845454 and ISBN 0471845450.
