Good day
I have issue to understand why in the second case we still have 1 degree of freedom, because according to my understanding ( the circles for me represent the trajectory of the rotation of the two segment, and according to it the two segments can't rotate simultaneously. but according to the book , in the second case the vertical displacement of point B is a allowed?
any hints would be highly appreciated thanks!
