An understanding of the terms, ‘struts, and ‘ties’ is important, as these can be mentioned in examinations. All structures have forces acting on them. You should have an understanding of tensile, compressive and shear forces (see previous sheet). The part of the structure that has a tensile force acting on it is called a TIE and the part that has a compressive force acting on it is called a STRUT.
|In the diagram below, forces act across the entire length of the beam (it bends because of the weight of the person). When a structure bends like this, it is in tension, as it is being stretched.|
|1. Draw an example of a structure and identify
which part(s) are in tension and which are in compression.
2. Explain the difference between tension and compression.
