Hi! I'm a first-year engineering student. I'm working on a project and was having trouble getting some of the software. I was hoping someone in this forum knew what I was dealing with and could help me out. I would really appreciate it. :) The code is called PLUTO. It's found here...

... but I haven't been around for a while! I joined this site a couple of years back but I haven't been all that active. Now that I'm in my second semester of first-year engineering at the University of Toronto, I'd say that's going to change. :) Nice to meet you all!

Thanks everyone! :) If the end of the rod was also be attached and pulling down on some mass M, would the torque also consider tension in the force?

Thank you but I am still unsure about the derivation.

Harvard University has an interesting article on a rod whose end that falls faster than gravity around a pivot. http://sciencedemonstrations.fas.harvard.edu/presentations/falling-faster-g How did they derive this formula? Where R is length of rod/2, or the centre of mass. Why did they use...

Ah! Thanks so much, I'm not sure why I'm having trouble visualizing this problem in particular. So in the design of a super fast chain would have as many bars as possible. Thanks so much again!

Brilliant! Thank you so much for the explanation. :) Very helpful! I have a followup question: I came to the derivation for acceleration of the free end of a rod with one end on the table and the other one in the air, angled at x. a=3/2×g×cos^2(θ) This means that the maximum acceleration would...

http://ruina.tam.cornell.edu/research/topics/fallingchains/chain_paperV13revised.pdf And this website summarizes it: http://ruina.tam.cornell.edu/research/topics/fallingchains/ Would something like this work as a workable derivation, even though it assumes the object starts at rest...

Thank you!

I am a Canadian student in grade 11. I love physics (though I'm not very good at it) so I hope this is the place to find out more about what I'm passionate about. I am currently interested in competing in the International Young Physicists Tournament. It's nice to meet you!

Hi! I am new to the forums and this is my first question. I am investigating the properties of this type of chain. In order to understand it better, I need to know the physics behind a falling angled rod. I understand that the other end speeds up to conserve momentum, but I do not understand...
