One type of wagon wheel consists of a 2.0-kg hoop fitted with four 0.80-kg thin rods placed along diameters of the hoop so as to make eight evenly spaced spokes. For a hoop of radius 0.38 m , what is the rotational inertia of the wheel about an axis perpendicular to the plane of the wheel and through the center?
3. A 1 m diameter wagon wheel consists of a thin rim having a mass of 8 kg and 6 spokes, each a mass of 1.2 kg. Determine the moment of inertia of the rim and the six spokes.
The wheels of a wagon can be approximated as the combination of a thin outer hoop, of radius ?h=0.527 m and mass 4.70 kg , and two thin crossed rods of mass 8.66 kg each. A farmer would like to replace his wheels with uniform disks ?d=0.0651 m thick, made out of a material with a density of 6450 kg per cubic meter. If the new wheel is to have the same moment of inertia about its center as the...
The wheels of a wagon can be approximated as the combination of
a thin outer hoop, of radius ?h=0.368 m and mass 4.32 kg , and two
thin crossed rods of mass 7.37 kg each. A farmer would like to
replace his wheels with uniform disks ?d=0.0462 m thick, made out
of a material with a density of 7370 kg per cubic meter. If the new
wheel is to have the same moment of inertia about its center as the...
The wheel shown consists of a thin ring having a mass of 15 kg and four spokes made from slender rods each having a mass of 1.8 kg. Determine the wheel's moment of inertia about an axis perpendicular to the page and passing through the center of rotation AND the moment of inertia about an axis perpendicular to the page and passing through point A.
6. A rigid sculpture consists of a thin hoop of mass m and radius R and two thin rods each of mass m and length L = 2R. The sculpture can pivot around a horizontal axis in the plane of the hoop passing through its center. What is the sculpture's rotational inertia I about the rotation axis in terms of m and R. rotation axis Answer | 1 = 58mR2
A 28.0 kg wheel, essentially a thin hoop with radius 1.00 m, is rotating at 320 rev/min. It must be brought to a stop in 11 s. How much work must be done to stop it? What is the required average power?
