Will the axis M-N rotate?

  1. Jun 22, 2016 #1
    1. The problem statement, all variables and given/known data
    A force F is applied over axis M-N in the such shown position. Both of points A and B are not fixed, and can slides inside the black fixed circle. will the applied force (in the shown position) cause the axis M-N to rotate ? if it is not rotating, then what modification should be made?

    Note that the distance A-M = N-B, and M-N's length is double the length of A-M.
    2. Relevant equations
    M = F*r

    M: Moment
    F: Force
    R=distance

    3. The attempt at a solution

    the force will generate equal moments at both points A and B. Anyhow, both of them will cancel each other, and thus no rotation will occur.

    What do you think mates?

    If you intended to post a diagram, none is showing up.

    I agree. No rotation. What about the last line of the question?
