Homework Help: Tension between two objects hanging

  1. Nov 18, 2006 #1

    How do we determine the tension of the string in the middle of the two objects? Let the tensions be T_1, T_2, and T_3, left to right:

    I tried

    [tex]\sum F_x = T_2 - \cos \theta T_1 = 0[/tex]
    [tex]\sum F_y = \sin \theta T_1 - mg = 0[/tex]

    for the other object it is similar. Is there something wrong with this? I can calculated T_2 without regard to the other object. Should I not include both the objects in F_y? thanx!

    If T2 is the tension in the middle string, this looks just okay.
