Physics Help Forum Bricks and rotation

So far I was thinking of trying to figure out how much the middle bricks can move outward and still have an angular acceleration $\displaystyle \alpha = 0$, but I'm not sure if that's a good approach or how to proceed (my skills in physics are rusty). Thank you in advance
