What is the coefficient of static friction between the button and the platform? - what is the smallest size gauge for plugs
A small button placed on a horizontal turntable with a rotor diameter of 0.326 m with a platform that min up to a speed of 42.0 rpm, when the push button located at a distance of 0.144 m axis.

Centripetal force = friction
mrω ^ 2 = μmg
rω ^ 2 = mg
(0.144 m) [(42.0 rpm) 2π (rad / rev) (min 60 s)] ^ 2 = μ (9.81 m / s ^ 2)
μ = 0.284
