5.107 A small bead slide without friction on a circu- lar hoop that is in a vertical plane and has a radius of 0.100 m. The hoop rotates at a constant rate of 4.80 rev/s about a ver- tical diameter (Fig. P5.107). (a) Find the angle B at which the bead is in vertical equilib- rium. (It has a radial accelera- tion toward the axis.) (b) Is it possible for the bead to "ride" at the same elevation as the center of the hoop? (c) What will happen if the hoop rotates at 1.00 rev/s?

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
