diameter. Each circle represents a solid disk which can spin about a perpendicular axis through the center of the disk. Draw in two forces on each disk. On one, draw the forces so that sigma vector F = 0 and sigma vector r neq 0. On the other, draw the two forces so that sigma vector F neq 0 and sigma vector r = 0. Keep all your forces in the plane of the disk. Make certain that you label...

2. A disk of radius 10.0 cm spins about an axis through its center at a constant 5.0 rad/s. What is the linear velocity, centripetal and tangential accelerations of a point on its rim? linear velocity = centripetal acceleration = tangential acceleration = 3. Under what conditions is the linear momentum of a system conserved? (Do not state when the initial is equal to the final.)

A disk rotates around an axis through its center that is perpendicular to the plane of the disk. The disk has a line drawn on it that extends from the axis of the disk to the rim. At t = 0 this line lies along the x-axis and the disk is rotating with positive angular velocity ω0z. The disk has constant positive angular acceleration αz. At what time after t = 0 has the line on the disk rotated through...

center. A ring with the same mass as the disk is attached around
the disk's rim. A tangential force of 0.237 N0.237 N applied at the
rim causes an angular acceleration of 0.129 rad/s2.0.129 rad/s2.

A space station shaped like a giant wheel has a radius of 127 m and a moment of inertia of 5.08 ✕ 108 kg · m2. A crew of 150 lives on the rim, and the station is rotating so that the crew experiences an apparent acceleration of 1g. When 100 people move to the center of the station for a union meeting, the angular speed changes. What apparent acceleration is experienced by the managers remaining at the rim? Assume...

You have designed a space station that rotates on its axis in
order to produce " artificial gravity." The space station has tree
levels consisting of rings connected to spokes that rotate about a
single axis as shown in the figure. The outer ring has a radius of
245 m.
a. what must the angular velocity of the space station be to
simulate the acceleration due to gravity on Earth's surface on the
outer ring of the space station?
