- A single bead can slide with negligible friction on a stiff wire that has been bent into a circular loop of radius 15.0 cm as shown in Figure P6.48. The circle is always in a vertical plane and rotates steadily about its vertical diameter with a period of 0.450 s. The position of the bead is described by the angle that the radial line, from the center of the loop to the bead, makes with the vertical. (a) At what angle up from the bottom of the circle can the bead slay motionless relative to the turning circle? (b) What If? Repeat the problem, this time taking the period of the circles rotation as 0.850 s. (c) Describe how the solution to part (b) is different from the solution to part (a). (d) For any period or loop size, is there always an angle at which the bead can stand still relative to the loop? (e) Are there ever more than two angles?

- An object of mass m1 = m and an object of mass m2 = 2m move around a rotation axis A in parallel circles of radii r1 = 2r and radii r2 = r, with tangential speeds v1 = 2v and v2 = v, as shown. As they rotate, forces of equal magnitude are applied opposite to their velocities to stop them. Which statement is correct? m2 will stop first because it has the smaller initial tangential speed Both objects will stop at the same time because their angular speeds are equal at all times m2 will stop first because it has the smaller radius m2 will stop first because it has a smaller moment of inertia m1 will stop first because it has the smaller initial angular velocity m1 will stop first because the torque on it is greaterarrow_forwardIf an airplane propeller rotates at 2000 rev/min while the airplane flies at a speed of 480 km/h relative to the ground, what is the linear speed of a point on the tip of the propeller, at radius 1.5 m, as seen by (a) the pilot and (b) an observer on the ground?
