AI Thread Summary
Using a single knot on the handle may not be the most effective method for tying a bucket to enhance spinning speed. Opting for a larger bucket can help create a bigger concave shape, reducing the need for high-speed spins. A longer rope can also facilitate prolonged spinning, allowing the water to achieve the desired paraboloid shape. Additionally, utilizing an old record player turntable set to 78rpm could provide an interesting alternative for achieving faster spins. Overall, experimenting with bucket size, rope length, and alternative spinning mechanisms may improve performance.

Is there a better way to tie the bucket than single knot on the handle? Or type of rope to use...that would increase speed of the spin? Mine just don't spin that fast at all.. Plastic bucket.. The concave is quite small compared to some I've seen done before.. Any better way to set it up?

Is it spinning long enough for the friction to get the water turning? You could try a bigger bucket. It won't need to spin as fast to get a big concave.
 
A very long rope will allow spinning to continue for longer - to allow the paraboloid shape to form and for other small perturbations to die out.

An old record player turntable, set to 78rpm is good - if you can find one.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
