radius

mass

tension force?

We did a lab where we connected rubber stoppers on one side of the string and masses to the other and spun it overhead and measured time taken for 10 cycles.

I came up with:

frequency is proportional to 1/(root(radius))

frequency is proportional to 1/(root(mass))

frequency is proportional to root(tension force)

from graphing... but I'm not sure if these are right...

I have to combine the three proportionality statements to get this equation:

sumF = 4pi^2mrf^2

Please help me~~~ T.T
