Homework Problem 6/38


Suggestions:
As always, use the four-step plan:
  1. FBD(s):  For part (a) you will need an FBD of the block in addition to one for the disk.
  2. Newton-Euler equations:  For part (a) you will need to use a Newton equation for the block along with the Euler equation for the disk. For part (b) you will need only an Euler equation for the disk.
  3. Kinematics:  For part (a) you will need to relate the acceleration of the block to the angular acceleration of the disk.
  4. Solve
Part (a) is very similar to the second example that we did in Wednesday's class. You can use that problem as a guide for this one.

Let us know if you have any questions on this.

Just checking, the a_block = radius*alpha right? This would be for the kinematics part.

Yes. And with a "+" sign.
