Homework Help: Is the system in translational equilibrium?

  1. Jan 31, 2008 #1
    Ok, I need to clear a little conceptual misunderstanding and I hope some of you will be kind enough to help me.

    Consider a mechanic turning a wrench about a nut. He exerts a force that is perpendicular to the wrench.

    Is the system in translational equilibrium? Is there a reaction force at the nut such that it will give a net resultant force of zero ?

    I too have two questions :-)

    Whether the center of mass of the wrench remains stationary?

    Whether the system with the nut is free to move and still remains in equilibrium?

    centre of mass of wrench does not remain stationary

    System is free to move and to display translational motion.

    Oh, I get it, if the system is not free to move, that means that there will be a reaction force at the nut correct??
