1 2 3 4 56 A uniform disk of mass 0.76 kg and radius 5.7 cm is mounted in the center of a 10 cm axle and spun at 795 rev/min. The axle is then placed in a horizontal position with one end resting on a pivot. The other end is given an initial horizontal velocity such that the precession is smooth with no nutation. 1) (a) What is the magnitude of the angular velocity of precession? rad/s Submit You...
A uniform disk with mass m = 8.91 kg and radius R = 1.31 m lies
in the x-y plane and centered at the origin. Three forces act in
the +y-direction on the disk: 1) a force 340 N at the edge of the
disk on the +x-axis, 2) a force 340 N at the edge of the disk on
the –y-axis, and 3) a force 340 N acts at the edge of the disk at
an angle θ =...

A purple bear is hinged to a wall to hold up a blue sign. The beam has a mass of 6kg and the sign has a mass of my - 16.1 kg. The length of the beam is L - 2.76 m. The sign is attached at the very end of the beam, but the horizontal wire holding up the beam is attached 2/3 of the way to the end of the beam. The ange the wire makes with the...
A block with mass m = 7.2 kg is attached to two springs with spring constants kleft = 29 N/m and Kright = 50 N/m. The block is pulled a distance x = 0.23 m to the left of its equilibrium position and released from rest. 7) Where is the block located, relative to equilibrium, at a time 1.31 s after it is released? (if the block is left of equilibrium give the answer as a negative value; if the...
A charged particle of mass m = 5.1X10-8 kg, moving
with constant velocity in the y-direction enters a region
containing a constant magnetic field B = 1T aligned with the
positive z-axis as shown. The particle enters the region at (x,y) =
(0.68 m, 0) and leaves the region at (x,y) = 0, 0.68 m a time t =
863 μs after it entered the region.
