The flexible ruler didn't work as well because the hammer, while exerting the same force, had more room to go because it managed to push the ruler out of the way instead of being stopped by it. Being a lever, it also brought both ends of the hammer (and, therefore, the center of mass) closer to the horizontal center, so it had less room to play with when it came to falling off of the table.
I think it's sad that a video entitle "funny cats" has about 35 million views (it is funny) while the majority of these sixtysymbols videos don't even break 50 thousand.
@SonOfNye Not sad, really. People have a lot of stress in their lives and problems they can't solve. If funny Cats make them laugh, makes them happy for a few minutes, what's wrong with that?
I would like to poke it too just to feel if it's tight, I suppose it's physics so it must be a tight concept for it to work correctly. It does seem to work better when it's stiff. The wood is much harder. Nice girl.
She left out the force exerted by the table upwards on the ruler. If there were no repulsion by the surface of the table on the ruler then it would pass through the table. It does not. There must be a force pushing upwards on the ruler in order for the ruler to push down also and the sum of those two vectors is zero. Also, there is a rotational torque at play in there causing the rocking back and forth of the ruler+hammer system.
@jalexoid: Another way to think of Newton's 3rd, which I find useful, is that a force always pushes in both directions, regardless of what the arrowhead says.
"The handle of the hammer is being pushed up this way, it's bending the ruler, and it's forcing this end of the ruler down to the table." Actually, no. The force down to the table is always the weight of the hammer, string, and ruler, independent of the upward force of the handle on the ruler, which changes depending where the string is tied. It is true though that the forces on the ruler from the table, string, and handle produce moments (vectors!) that sum to zero. :)
do you find that you have to "dumb it down" with the explanations of your videos, i seem to follow along very well in all the videos so far, but it seems that it would be more complicated than it apears in the video.
a friend of mine who goes to Nottingham University told me that they say exactly what they say in the video in the beginning of the lectures and then they move on to the complicated stuff
man that was cool my university professor went over vectors but it wouldve been soo much better if they did that experiment.

There is a thing that is called Newtons 3rd law. And it is implied, sine it's one of the most basic laws of physics.
"To every action there is an equal and opposite reaction." equates to "force exerted by the table upwards on the ruler".

You should slow down and replay the video of the first hammer falling so that the point of imbalance and failure can be demonstrated as well.
