Problem Check: Equilibrium of Particles

  1. Feb 11, 2015 #1
    1. The problem statement, all variables and given/known data
    A continuous cable of total length 4 m is wrapped around the small pulleys at A, B, C, D. If each spring is stretched 300 mm, determine the mass m of each block. Neglect the weight of the pulleys and cords. The springs are unstretched when d=2 m.

    3. The attempt at a solution

    I just need someone to tell me if I've done this correctly. Thank you!

    it stopped as a square! (very special case) where the spring tensions are equal the weights. looks right.
    there will be lots of "accidentally correct" (or lucky guess, then check) answers to this one!
