A small bead can slide without friction on a circular hoop that is in a vertical plane and has a radius of 0.100 m. The hoop rotates at a constant rate of 4.00 rev>s about a vertical diameter (Fig. P5.107). (a) Find the angle b at which the bead is in vertical equilibrium. (It has a radial acceleration 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?

Question
A small bead can
slide without friction on a circular hoop that is in a vertical plane
and has a radius of 0.100 m. The
hoop rotates at a constant rate of
4.00 rev>s about a vertical diameter (Fig. P5.107). (a) Find the
angle b at which the bead is in
vertical equilibrium. (It has a radial acceleration 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?
