Study Guide

Objectives

The students learn to understand the basics of strength of materials as well as the most important strength properties of wood and steel. They know the different stresses and the dependencies between strain, stress and transformations. The students understand how the cross-section, shape, size and material affect the stress and transformations. The students are able to calculate the strain of a straight rod for different forms of strain as well as to measure a buckling rod.
