Can you Calculate the Degree of freedom of this mechanism? | Theory of Machines

[@cyracuse1703]

I am new to this topic. Could someone help me understand as to why all "ground" connections are considered to be just 1 link? If we number the other fixed joints like the ground one, there should be two more links, shouldn't there? Apologies if I am wrong. I just want to know the theory behind it. Thanks in advance!

Can we calculate dof of car parking ?

The structure consist of 4 bars and 4 rollers , two support plates , bottom is fixed , top is moving

[@jhonnywalker6632]

There is no ternary link triangle is considerd as single link and the turning pair along with sliding pair is considered as redundant motion .

You can't move that link with the remaining mechanism at rest. So it's not a redundant degree of freedom.
