The sphere of mass M and radius R is rigidly attached to a thin rod of radius r
A rod of length L and negligible mass is attached to a uniform disk of mass M and radius R (see figure below).
A rod of length L and negligible mass is attached to a uniform disk of mass M and radius R (see figure below). A string is wrapped around the disk, and you pull on the string with a constant force F. Two small balls each of mass m slide along the rod with negligible friction. The apparatus starts from rest, and when the center of the disk has moved a distance d, a length of strings has come off the...

As in the figure, a uniform sphere of mass = 0.84 kg and radius r = 4.2 cm is supported by a string (of negligible mass) attached to a wall (whose friction can also be ignored). The center of the sphere is a vertical distance L = 10 cm below the attachment point of the string. Find the tension in the string. (Note that the direction of the tension (along the string) is along a line passing through the center...

An object is formed by attaching a uniform, thin rod with a mass of mr = 7.31 kg and length L = 5.68 m to a uniform sphere with mass ms = 36.55 kg and radius R = 1.42 m. Note ms = 5mr and L = 4R. *What is the moment of inertia of the object about an axis at the left end of the rod? *If the object is fixed at the left end of the rod, what...

M, a solid cylinder (M=1.39 kg, R=0.111 m)
pivots on a thin, fixed, frictionless bearing. A string wrapped
around the cylinder pulls downward with a force F which equals the
weight of a 0.570 kg mass, i.e., F = 5.592 N. Calculate the angular
acceleration of the cylinder. (the answer to this is 39.8 rad/s^2)
