How do the hanging mass and rotating mass affect velocity/centripetal acceleration? You know the centripetal force apparatus where you use a rubber stopper (rotating mass) and washers (hanging mass)? Yeah i am talking about that. I am wondering if the hanging mass and rotating mass affects the velocity. I looked for velocity calculators like this one
http://hyperphysics.phy-astr.gsu.edu/hbase/cf.html#cfc
but the Mass field doesn't state if it includes both hanging/rotating mass so i am confused.

I am asking if changing the hanging mass affect velocity. Does that go through your thick skull, anilbakshi?

The formula for centripetal acceleration is m v^2 /r.
The mass in this formula is the mass of the object which is revolving in circular orbit.
I think this is your question.
The mass of the hanging mass is not included in this formula.

In the apparatus you seem to be describing, the force balance equation is
Mh = hanging mass
Mr = rotating mass
g = acceleration due to gravity
v = tangential velocity or speed
r = radius
Mhg = Mrv^2/r
v^2 = rMhg/Mr = (Mh/Mr)rg
v = â((Mh/Mr)rg)

Vague description man! Just remember F=ma, torque, amgular acceleration and inertial mass.
