A small button placed on a horizontal rotating platform with diameter 0.324 m will revolve with the platform when it is brought up to a rotational speed of 45.0 rev/min , provided the button is a distance no more than 0.141 m from the axis. What is the coefficient of static friction between the button and the platform? How far from the axis can the button be placed, without slipping, if the platform rotates at 64.0 rev/min ?

A small button placed on a horizontal rotating platform with diameter 0.324 m will revolve with the platform when it is brought up to a rotational speed of 44.0 rev/min , provided the button is a distance no more than 0.141 m from the axis. A) What is the coefficient of static friction between the button and the platform? B) How far from the axis can the button be placed, without slipping, if the platform rotates at 62.0 rev/min ?

A small bead of mass m can slide without friction on a circular hoop that is in a vertical plane and has a radius R. The hoop rotates at a constant angular velocity ω about a vertical axis through the diameter of the hoop. Our goal is to find the angle β, as shown, such that the bead is in vertical equilibrium. We break the problem into several steps. a) Assume the bead is in vertical equilibrium and does not...

(Cross identities only) A large flat horizontal platform rotates at a constant angular speed ω. A person on the platform walks in a circular path of radius R0 centered on the axis of the platform with a constant linear speed v relative to the platform’s surface. The coefficient of friction between the person and the platform’s surface is µ and the mass of the person is m. How fast can the person walk if: (a) they move in the direction...
