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...

The radius of a wheel is 0.410 m. A rope is wound around the outer rim of the wheel. The rope is pulled with a force of magnitude 3.63 N unwinding the rope and making the wheel spin counterclockwise about its central axis. Ignore the mass of the top. (a) How much rope unwinds while the wheel makes 2.74 revolutions? d= __7.06__ m (b) How much work is done by the rope on the wheel during this time? W= _____...

A drum of 60-mm radius is attached to a disk of 120-mm radius, The disk drum have a total mass of 6 kg and a combined radius of gyration of 90 mm. A cord is attached and pulled with a force P of magnitude 20 N, Knowing that the disk rolls without slipping, If the angular acceleration of the disk is 20 rad/s^2 what is the acceleration of the center of mass of the system (Wheel with center G and...

6. Consider the system shown: m, J, R The wheel with mass m, radius R, and rotational moment of inertia J rolls without slipping down the incline shown. The spring affixed to its axle has rest length h, and is neither extended nor compressed when r 0. The external force F is directed parallel to the direction of rolling. Find the total kinetic energy and potential energy in the system. Assume the gravitational potential energy to be zero when the...

Chapter 11, Problem 081 A uniform wheel of mass 10.0 kg and radius 0.400 m is mounted rigidly on an axle through its center (see the figure). The radius of the axle is 0.200 m, and the rotational inertia of the wheel-axle combination about its central axis is 0.600 kg-m2. The wheel is initially at rest at the top of a surface that is inclined at angle 58.4° with the horizontal; the axle rests on the surface while the wheel...

In the figure, a very light rope is wrapped around a wheel o radius R = 2.0 m and does not slip. The wheel is mounted with frictionless bearings on an axle through Its center. A block of mass 14 kg is suspended from the end of the rope. When the system is released from rest it is observed that the block descends 10 m in 2.0 s. What is the moment of Inertia of the wheel?
