Homework Help: Double tension problem

  1. Feb 24, 2013 #1
    Im getting stuck on the fnet equation for the middle box. I dont really know where to start I can get the two fnet=ma equations for the boxes hanging and how do the boxes hanging on each side effect the system as a whole.
    Thanks I know this is most likely an easy question !

    The first thing is to figure out which way friction will act on the middle box.
    Post whatever you have.
