WebThe strain development of the tube was measured by strain gauges. At the height level of the middle of the defect, four pairs of strain gauges were symmetrically stuck on the external surface of the tube to record the strain distribution on this cross-section (Points 1–4). More details about the strain gauges were shown in Fig. 4 b). 2.4. WebLearning Objectives. After this lesson, students should be able to: Recognize that engineers use their understanding of forces, stress, strain and material properties to create safe designs for structures, equipment and products. Explain how force and area affect stress. Distinguish between compression and tension.
