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?

Problem: A pulley, consists of a disk of radius R=0.2 m and mass M= 50 kg is mounted on a nearly frictionless axle. A string is wrapped lightly around the pulley, and you pull on the string with a constant force, F = 100 N. If the pulley starts from rest, what is the angular speed at a time At = 1 s later? Assume that the string does not slip on the pulley. Note: Moment of inertia of a...

(1) A thin stick is glued to a uniform disk to form a composite pulley. Then a non-slip string with two masses is hung over the disk and the system is released from rest. Uniform Disk mass: 4 kg radius: 5 cm Calculate the moment of inertia of the stick plus disk combination and find the angular acceleration of the composite pulley, the linear acceleration of the two hanging blocks, and the tensions in each part of the string (which...

The pendulum in the figure consists of a uniform disk with radius r = 11.0 cm and mass 400 g attached to a uniform rod with length L = 410 mm and mass 250 g. (a) Calculate the rotational inertia of the pendulum about the pivot point. (b) What is the distance between the pivot point and the center of mass of the pendulum? (c) Calculate the period of oscillation.
(Figure 1) A thin rod of mass mr and length 2L is allowed to pivot freely about its center, as shown in the diagram.
Pivoted Rod with Unequal Masses (Figure 1) A thin rod of mass mr and length 2L is allowed to pivot freely about its center, as shown in the diagram. A small sphere of mass m1 is attached to the left end of the rod, and a small sphere of mass m2 is attached to the right end. The spheres are small enough that they can be considered point particles. The gravitational force acts downward, with the magnitude of the gravitational acceleration...

A compound pendulum is made up of a rod of length L, with mass M and a solid sphere of radius r, with mass m (see figure below). The pendulum is pivoted about one end and released from rest from and angle of 0, (angle with the vertical). (a) Find the distance, dom, of center of mass of this pendulum from its pivot. (b) Draw a free body diagram and write down Newton's 2nd Law (for rotation) for the pendulum...
