    Do you mean the set-up in the figure attached?

    Draw the free body diagrams for all blocks. What are the conditions that the blocks are static?

    think of how m1 can be static. the force on the other side of the rope can be difficult, think carefully about how m2 and m3 contribute. perhaps apply f=ma to the pulley; the result is interesting
