Homework Statement


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.

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!
