Can you find tension on a string without mass

  1. Sep 30, 2015 #1
    So my pulley system has 3 masses two of which are connected to a center mass on top of a table. No mass was given for any of the objects but of two masses hanging from the table, the one on the right is 2 times the mass on the left. I hope I haven't confused you but its like a three step diagram so i'm going to try make a picture for you

    M2(free weight)-----^M1(on table)------M3(free weight,X2 the mass)

    Are the weights supposed to be in mechanical equilibrium? I recommend drawing a free body diagram for each mass.

    Yes they are and I have! it was also given with a free body diagram that's why I tried to draw it out for you

    What forces do you get acting on each mass? What happens when you set the sum of the forces on each mass to zero?
