Objectives
After the course, the student can calculate the normal stress, shear stress and bending stress distributions for regularly shaped cross-sections caused by external loads. In addition, the student knows how to calculate the deformations caused by normal force and bending moment for regularly shaped cross-sections.

The student knows the effects of the shape, size and material of the cross-section of the structure on stresses and deformations, as well as being able to calculate the strength theoretical quantities of the reduced cross-section. The student knows how to calculate the stresses and deformations of a straight rod for bending and shear, and to dimension a buckling rod.
