It is 2000 kg-mass, yes. How would I go about treating the pulley as one? Since it's the same cable going through D and E, do I not need to apply it to the links multiple times?
So far I have used methods of joints to determine the forces at point E, D, and C. However, there is also a pulley attached to point D and E which I included in the sum of forces, but I'm not sure if that's the correct way to apply them. Every force I've calculated so far has also been in...
