Confused a bit by your use of translate - to change to another language or to change to another form.
Presume you mean rotate but if so the question is too simplistic.
What you have described is a perfect moment and if you keep the forces normal to the plank it will spin up like a prop.
If you maintain the direction of the forces then the plank will turn through 90 degrees and stop.
I think I must be wrong in interpreting what you mean.
