Beams,and one roller, and this is called simply supported. Another common beam type is the cantilever, as shown in . Here one end is unsupported but the other must be rigidly built-in to prevent rotation. The third reaction force has now become a moment or couple, but more of that later. A simply supported beam can have a cantilever-end as shown in

Basics,ith the mechanics of forces applied to bodies which are not moving. They are said to be in . Although much of this material may be familiar, it is worth ensuring that you fully understand it because it is fundamental to the rest of the book.

Loads,hat can act on a structure, and then goes on to explain how the loads carried by individual structural members are calculated, this vital stage in the design process can be quite tricky — particularly if it is necessary to analyse an old existing structure.

Tension, loads are only applied at the nodes. We also saw how such structures can be analysed to determine the magnitude of the force in each member. This chapter considers the . of members in pure tension, i.e. for a known tensile load, what are the actual required dimensions of a steel or aluminium tie to
