Basics of Structural MechanicsLaajuus (5 cr)

Objective

After completing the course, the student can compute internal structural stresses and deformations using fundamental theories. They understand strength properties of materials and concepts related to stresses and strength. They know basic concepts of structural mechanics, such as rod tension, compression and torsion, beam bending, rod forces in trusses and rod buckling. The student can compute normal and shear stresses of a statically determined bent beam and deflections of simple beam structures. They know the basics of cross-sectional quantities. They know dimensioning principles of structures.
