1)
A man holds a wire from which a mass m1 hangs, a second wire below it connects to a hanging mass m2, and a third wire connects the second mass to another mass m3. If the system remains at rest and the cables have no mass, what force is the man doing with his hand? What is the tension in each of the 3 cables?
2)
A rope with diameter d, length l and density ρ hangs vertically. What tension produces the weight of the rope at its upper end? What tension does it produce in the center of the string?
