For example this is the reading at the first joint. And you can see that the rotation at the first joint will increase. At this point the second link locks and then it starts vibrating. And after a while and also moving, and after a while the first links also locks and it is stationary. So, one of the motivation is to see whether we can model flexible systems such as this and whether we can reproduce this experimental data. Because if we can reproduce this experimental data by means of mathematical modelling then we do not have to conduct these expensive experiments every time.
