Objectives: Students will become familiar with the concepts of work, conservative forces and potential energy. In addition, they will become acquainted with the principle of virtual work. After studying this chapter, students should be able to correctly apply this principle in order to determine equilibrium states in nonrigid systems as well as support reactions and internal forces and moments. Finally, it will be shown how to investigate the stability of equilibrium states of conservative systems with one degree of freedom.
