what would you suggest I use as alternative materials?

I am not trying to go crazy I figure I would need a massless suspension/aircraft cable, a frictionless pivot, and a hollow bob. I am going to head over to the engineering lab next week so that I can work out some numbers. Is there a website online I can order from? or possibly a place around...

Hey everyone My name is Brad I am a undergrad going to to school for chemistry and physics. This is my first time joining a science forum and it seems amazing. You will probably see me in the homework and general questions area as I am just scratching the surface for theoretical and more...

(I apologise if this is the wrong area to post) Hello everybody I am planning on building my first Focault Pendulum(As a physics projject for school) and I have a few questions. I am going to purchase a cable(it needs to be smooth and friction-less around 7 feet), I also am going to need to...
