Then what would be the correct answer?

Wouldn't the answer still be the same?

It's actually in lbs. I don't know why I wrote 45.2N. The answer is supposed to be in lbs. And about the direction of F(p), I assumed it would be horizontal since the beam is in static equilibrium while remaining horizontally.

I have been trying to work on this problem, but I keep getting the answer wrong. I would appreciate if someone could help me understand what I did wrong. Below is my answer and solution:

That's exactly how the experiment goes. One disk is rotating while the other is dropped from rest. Immediately after, they both begin to rotate at the same speed.

So is the torque that rotates the stationary disk is caused by the force of friction? The next questions asks to explain why this torque (that rotates both disks) can't account for experimental discrepancies between the final and initial angular momentum, given that we neglected friction in the...

Suppose I have a system of two disks (identical in mass and size) one is fixed to a shaft at it's center point and rotating due to an external torque that's removed as soon as the rotational motion begins. The second disk is dropped from rest over the rotating disk and sticks together to the...
