More than just a book, this volume is part of a system to teach engineering mechanics, a system comprised of three 1) this core principles book, 2) algorithmic problem material available online, and 3) a course management system to track and monitor student progress. KEY TOPICS Chapter topics cover vectors, forces, systems of forces and moments, objects in equilibrium, structures in equilibrium, centroids and centers of mass, moments of inertia, friction, internal forces and moments, and virtual work and potential energy. For individuals preparing for a career in engineering mechanics.
