Is the system in translational equilibrium?

[Oerg]

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 ?

any help?

 

[Oerg]

is there something wrong with my question :sigh: last and final bump

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?

 

[Oerg]

ok,

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??
