The figure shows a rigid
assembly of a thin hoop (of mass m = 0.27 kg and radius R = 0.17 m)
and a thin radial rod (of length L = 2R and also of mass m = 0.27
kg). The assembly is upright, but we nudge it so that it rotates
around a horizontal axis in the plane of the rod and hoop, through
the lower end of the rod. Assuming that the energy given to the
assembly in...

An object consists of the thin rod of mass 3M and length R and the disk of mass 2M and radius R attached to the rod. The object can (freely) rotate around the pivot passing through the point O and being perpendicular to the rod as shown in the Figure above. What is the moment of inertia of the rod with respect to the axis of the rod with respect to the axis of rotation?

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?

The figure shows a rigid structure consisting of a circular hoop of radius R and mass m, and a square made of four thin bars, each of length Rand mass m. The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of 3.5 s. If R = 1.2 m and m = 3.3 kg, calculate the angular momentum about that axis. Rotation axis Number Units

The figure shows a rigid structure consisting of a circular hoop of radius R and mass m, and a square made of four thin bars, each of length R and mass m. The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of 4.3 s. If R = 1.1m and m = 1.8 kg, calculate the angular momentum about that axis.

The figure shows a rigid structure consisting of a circular hoop of radius R and mass m, and a square made of four thin bars, each of length Rand mass m. The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of 2.1 s. If R=0.9 m and m-4.0 kg, calculate the angular momentum about that axis. Number i Units

6. (BONUS) Two particles each with mass m = 0.4 kg, are fastened to each other, and to a rotation axis at 0, by the two thin rods, each of length d and mass M = 1.5 kg as shown below. The combination rotates around the rotation axis with angular speed w = 0.2 rad/s. The total moment of inertia of the system measured about O is 2.3 x 10-4 kg m?. (Hint: The moment of inertia of a thin...

A uniform cylinder of radius r15.0 cm and mass m 1.70 kg is rolling without slipping on a horizontal tabletop. The cylinder's center of mass is observed to have a speed of 4.60 m/s at a given instant. (a) What is the translational kinetic energy of the cylinder at that instant? J (b) What is the rotational kinetic energy of the cylinder around its center of mass at that instant? J (c) What is the total kinetic energy of the...
