The notes do not stand complete by themselves; rather, they contain spaces for students to fill in during lectures. OBJECTIVES To develop an understanding of the behaviour of structural or machine components under various loading conditions. Structural components are treated as solid elastic bodies that deform under applied external loading conditions. This course will allow students to understand how external forces are transmitted through the structure (as internal forces) to its supports, thus giving rise to support reactions. Furthermore, internal forces produce elastic deformations in the given structure (which are often discussed in terms of strains), as well as stresses. Students will also learn how to locate the maximum stress component at a point in the socalled critical cross-section for different types of simple loading conditions, such as axial forces, direct shear forces, bending moments, and torsional moments. Using the principle of superposition, the various stress components will then be combined for application to more realistic problems. The displacements caused by these various loading types will also be presented. Time permitting, students will also study the stability of columns (i.e. buckling) and impact loading.
