Place 0.150kg (including the mass of the hanger) at a position somewhere between 0 degrees and 90 degrees. (I chose 45 degrees for this problem.) Place the second pulley at exactly 180 degrees and the third pulley at exactly 270 degrees. Determine how much mass you must place on the second and third pulleys for the system to be in equilibrium.
I am really not sure about how to approach this problem, any help would be greatly appreciated. Thank you!
