17. [1pt) A wheel of mass m = 1.87 kg and moment of inertia, I = 1.530 kg.m- is supported by a pivot a distance d=0.17 m from the wheel, as shown in the diagram. The axle through the wheel is initially in the horizontal plane, as shown, and the wheel is spinning about the axis in the sense indicated, with an angular velocity o = 90 rad's. Answer the following three questions using the choices given; c.g., if the...

Up A #4. [Gyroscope Wheel] A rubber wheel on a steel rim spins freely on a horizontal axle that is suspended by a fixed pivot at point P. When the wheel spins at a rate of 4.00 rev / s, it precesses smoothly about point Pin a horizontal plane with a period of 3.50 s. The wheel's outer radius is 15.0 cm, and it's total mass is measured to be 1.12 kg, 60% of this being the spinning wheel and...
A 2.0 m measuring stick of mass 0.165 kg is resting on a table. A mass of 0.500 kg is attached to the stick at a distance of 74.0 cm from the center. Both the stick and the table surface are frictionless. The stick rotates with an angular speed of 5.40 rad/s. a)If the stick is pivoted about an axis perpendicular to the table and passing through its center, what is the angular momentum of the system? b)If the stick...
A woman with mass 50 kg is standing on the rim of a large disk that is rotating at 0.80 rev/s about an axis through its center. The disk has mass 270 kg and radius 4.0 m. Calculate the magnitude of the total angular momentum of the woman–disk system. (Assume that you can treat the woman as a point.) Express your answer to two significant figures and include the appropriate units.
A centrifuge rotor rotating at 9500 rpm is shut off and is eventually brought uniformly to rest by a frictional torque of 1.93 m⋅N . If the mass of the rotor is 4.69 kg and it can be approximated as a solid cylinder of radius 0.0600 m , through how many revolutions will the rotor turn before coming to rest? How long will it take? Express your answer to three significant figures and include the appropriate units.
