Homework Statement


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.

Homework Equations


M = F*r

M: Moment
F: Force
R=distance

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?[/B]

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