Note: I am in Algebra-based Physics

Two 35.0 N weights are suspended at opposite ends of a rope that passes over a light, frictionless pulley. The pulley is attached to a chain that is fastened to the ceiling. Start solving this problem by making a free-body diagram of each weight.

What is the tension in the rope?
Answer should be expressed in N.

What is the tension in the chain?
Answer should be expressed in N.

What would happen on this question if you welded the chain to the pulley? Would that change anything? Doesn't tension equal the static forces holding the chain?

Please in the future post your thinking or work. You wouldn't want anyone to think you were an answer moocher.

I don't know how to get started! That's the problem!!!

Two persons pulling on a rope, each with force F. The tension by definition is F.
