21. What is a pin-jointed structure in reality

As with all models we use in our analyses, they're an approximation of the behaviour of the real structure. As such their behaviour will be different depending on the simplifying assumptions we make. In this lecture we focus on some of the important differences between our analysis models and real trusses. By the end of this lecture you will have an appreciation for how your analysis relates to reality.
