More specifically:
[tex]\alpha=(r*F)/(.5mr^2)[/tex]

I know I'm getting the acceleration just fine. I've then been using:
[tex]\omega^2 = 2\alpha\Delta\Theta[/tex]

I know the problem is coming in here. Probably in conversion of units (rad/s^2) to (rev/s^2) or something along those lines.

The ball hangs on the right end of the block, the first support is on the left end of the block and the second support is 1.5 meters away from the left end of the block.

I've been trying all sorts of things, including:
L = 2.0 m
d = 1.5 m
F2 = mg(L/d)
F1 = mg - F2

I'm pretty sure the answer should be negative.. but i don't have it right yet.

Yeah.. that equation isn't working for me. Why (L-1), btw? And mass of the ball.. are you dividing the N value by 9.81 or did you mean the force of the ball (in N)?

Here's a site I found with the same problem. You can view the correct answers and try to work to it, but I still haven't figured out the proper equation yet.

MY MISTAKE: just noticed "Then you need to find your delta x, which you do by multiplying the radians you found in the above by your radians (don't forget to convert cm to m!!)"

WHEN I SAID MULTIPLYING THE RADIANS YOU FOUND ABOVE BY YOUR RADIANS, I MEANT YOUR RADIUS.
