How do you calculate the speed/acceleration of a disk placed

goodluck.
no one on this board has any applied experience.
they like to stick to non-physics related brain games.

once u start adding real variables they lose their shit and just lash out

>>8592970
obviously you have to count how many times the disk revolves per second
did you think the answer was more complicated than that

case in point

Nothing I'm capable of figuring out.

t. physics grad

Fuck you faggot! I bet you know nothing about numerical typology!

Answer the question!!

sci is supposed to be the smart guys

1. Figure out how much string is shortened by being twisted.
2. Multiply by force to get work done on string.
3. Calculate the rotation of the disk when it gets the kinetic energy.

Come on guys how else am I going to calculate how hard I need to pull to make the pepperonis fly off

How would you even go about setting up the question

Here's an equivalent question setup:
A disk with radius R, height H and mass Mr has a string with diameter D, length L and mass Ms passing through the center. Assume uniform density in the disk and uniform linear density in the string. The string is fused to the disk such that if the string rotates, the disk rotates as well (L-H of the string is inside the center of the disk). The string is twisted N times while the bottom is pinched, such that it will not rotate until released. After it is released and it has twisted N times in the opposite direction, what is its speed?
Obviously there's more factors (as in, what the string is made of and whatever material properties needed) involved, but neither I nor OP knows those factors and how to account for them.

What is a...numeral topical?
