Why Machines That Bend Are Better

Compliant mechanisms have lots of advantages over traditional devices. SimpliSafe is awesome security. It's really effective, easy to use, and the price is great. Check out SimpliSafe here: simplisafe.com/veritasium
I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:
At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.
What I learned about compliant mechanisms I summarize in the 8 P's of compliant mechanisms:
1. Part count (reduced by having flexible parts instead of springs, hinges)
2. Productions processes (many, new, different enabled by compliant designs)
3. Price (reduced by fewer parts and different production processes)
4. Precise Motion (no backlash, less wear, friction)
5. Performance (no outgassing, doesn't require lubricant)
6. Proportions (reduced through different production processes)
7. Portability (lightweight due to simpler, reduced part count designs)
8. Predictability (devices are reliable over a long period of time)

I would think this video is a bit misleading no? Really only plastics and other flexible materials can be used as far as I am concerned (not too familiar on plastics). But this certainly would not be good for metal applications. Metals are known to fall victim to metal fatigue. For example, chains have zero moving parts and zero bending parts. However, chains have been known to spontaneously fail below their specified rates, and they have zero moving and bending parts. I couldn't imagine something like that titanium hinge falling under the same circumstances, and probably even worse because of the bending crystal structure. Although its great if its not being used a lot (if that's what NASA intended).

This is very interesting. I've always thought that nothing in this world is perfectly "good" or "bad" for the application. I think, just like how Professor Larry Howell thought of using flexibility towards benefiting the design, there's ALWAYS a way to turn something into good. Would love to incorporate this into my capstone project!

In primary school we had a mini contest to see who could make the best kinex(I think that’s what it was) catapult and fling a bit of paper. It was super obvious to me but I was the only one to use a long thing and bend it. I won. This story is so random but I find it funny.

Veritasium what would happen if you had Abdul Qadeer Khan (AQ Khan) on your channel? He developed the nuclear weapons program for Pakistan. Just because you have a western professor on does not make him any less repulsive than AQ Kahan. We should be dismantling weapons of mass-destruction not showing off the mechanisms which make them more effective.
