Let's look at what is happening to the strain since the dynamic equations of motion have strain, the rigid variables as well as the flexible variables we can calculate the strain. If you look at the strain for about the initial 2.9 seconds it is very small, we cannot measure it. Then at the time when the first locking takes place the whole links start, the whole structure starts to vibrate as well as move. And then somewhere here, the simulation says around a little after 5 seconds we have this locking of the second joint and then this whole thing again vibrates. This is the strain in the first link, at the base of the first link. Similarly, we can find the strain at the base of the second link which looks like this. This is what the simulation tells us.
