A top spins at 25.0 rev/s about an axis that makes an angle 36.0o with the vertical. The mass of the top is 0.5 kg, its rotational inertia about its central axis 4.0×10-4 kg*m2, and its center of mass is 6.0 cm from the pivot point. If the spin is in the counterclockwise from an overhead view, what is the (a) precession rate? ( compute in rev/s but DO NOT enter units)

    A top spins at 65.0 rev/s about an axis that makes an angle 30.0o with the vertical. The mass of the top is 0.5 kg, its rotational inertia about its central axis 7.0×10-4 kg*m2, and its center of mass is 7.0 cm from the pivot point. If the spin is in the counterclockwise from an overhead view, what is the (a) precession rate?

    The moment of inertia of the human body about an axis through its center of mass is important in the application of biomechanics to sports such as diving and gymnastics. We can measure the body's moment of inertia in a particular position while a person remains in that position on a horizontal turntable, with the bodys center of mass on the turntable's rotational axis. The turntable with the person on it is then accelerated from rest by a torque that...

    A cylinder with rotational inertia I1 = 3.2 kg · m2 rotates clockwise about a vertical axis through its center with angular speed ω1 = 5.8 rad/s. A second cylinder with rotational inertia I2 = 1.2 kg · m2 rotates counterclockwise about the same axis with angular speed ω2 = 6.2 rad/s. If the cylinders couple so they have the same rotational axis, what is the angular speed of the combination (in rad/s)? What percentage of the original kinetic energy...

    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 figure-skater finishes her routine with a dramatic spin. Initially, she spins at a rate of 1.3 rev/sec

    A figure-skater finishes her routine with a dramatic spin. Initially, she spins at a rate of 1.3 rev/sec. During this time, the figure skater has her arms stretched out. In each hand, she holds a mass of 2.3 kg at a distance of 0.65m from the center of her body. She then pulls her arms in so that the masses are tucked into the middle of her chest. The moment of inertia of her head-torso-legs remains fixed at 24 kg-m2....

    A student sitting on a stool that is free to rotate (frictionless), but is initially at rest, holds a bicycle wheel.  The wheel has a rotational velocity of 10 rev/s about a vertical axis counter clockwise (vector of angular momentum points up).  The rotational inertia of the wheel is 4 kg*m2 about its center and the rotational inertia of the student and wheel and platform about the rotational axis of the platform is 12 kg*m2. If the student flips the axis of...

    3-axis center of mass FIGURE 8.24 Problem 20: (Tippe top) This simple device appears to defy the laws of classical mechanics. Start it spinning, and it eventually inverts, raising its center of mass to a higher position, where it spins happily until it runs down. We will examine this strange behavior qualitatively here. The top has a mass M and radius R. The center of mass is a distance a from the center of the sphere as shown in Figure...
