| adam_text | This book covers the essential elements of engineering mechanics of deformable
bodies, including mechanical elements in tension-compression, torsion, and bending.
It emphasizes a fundamental bottom-up approach to the subject in a concise and
uncluttered presentation. Of special interest are chapters dealing with potential energy
as well as principle of virtual work methods for both exact and approximate solutions.
The book places an emphasis on the underlying assumptions of the theories in order
to encourage the
readerto
think more deeply about the subject matter. The book should
be of special interest to undergraduate students looking for a streamlined presentation
as well as those returning to the subject for a second time. Solutions to the end of
chapter exercises are available on request for instructors.
