Make a wish... Homework 11.

Lyric of the day
These crazy ideas, oh they don't last long
But they come and they go in America

For Problem 3. I was able to solve for the angular acceleration of the bar. From there I am having trouble relating that value to the acceleration to the block. Since the block is mass less when summing the forces, would that term equal zero? If that's the case then I feel like we would have to relate the acceleration of G to B using planar mechanics. From here I'm having difficulty.

The equations of motion should have resulted in equations with the acceleration of the block as one of the unknowns. If you solved those for the angular acceleration you can substitute that (the angular acceleration) back in to find the acceleration of the block. This is very similar to the example that we did in class...

Will you provide the solution to Problem 4?
