A device is made of a wheel with an inner drum and is mounted on a frictionless axle so it does not translate but can rotate about its centre. As indicated in the figure, this device is used to lift a 30.0 kg box. The outer radius R of the device is 0.500 m and the radius of the inner drum is 0.200 m. A constant horizontal force F of magnitude 140 N is applied horizontally, as shown, to a...
A disk-shaped (radius = 0.20 m) is mounted on a frictionless, horizontal axis. A light cord wrapped around the wheel supports a 0.50-kg object. When released from rest the object falls with a downward acceleration of 5.0 m/s^2. What is the mass of the pulley? Please show all the steps and diagram.
In
the figure below, a wheel of radius 0.15 m is mounted on a
frictionless horizontal axle. A massless cord is wrapped around the
wheel and attached to a 2.0 kg box that slides on a frictionless
surface inclined at angle θ = 25° with the horizontal. The
box accelerates down the surface at 2.1 m/s2. What is
the rotational inertia of the wheel about the axle?

1. A pulley (radius = 0.20 m) is mounted on a frictionless, horizontal axis. A nearly massless string is wrapped around the pulley and supports a hanging mass of 0.55kg. When released from rest the mass falls with a downward acceleration of 5.1 m/s. What is the moment of inertia of the pulley? (8pts) el (@9
Your answer is partially correct. A wheel of radius 0.486 m is mounted on a frictionless horizontal axis. The rotational inertia of the wheel about the axis is 0.0240 kg-m. A massless cord wrapped around the wheel is attached to a 2.91 kg block that slides on a horizontal frictionless surface. If a horizontal force of magnitude - 3.52 N is applied to the block as shown in the figure, what is the angular acceleration of the wheel? Take the...

011 10.0 points A uniform disk of radius 0.31 m is mounted on a frictionless, horizontal axis. A light cord wrapped around the disk supports a 1.5 kg object, as shown. When released from rest the object falls with a downward acceleration of 4.6 m/s?. MacBook Air r
A yo-yo of mass m and radius R is placed on a horizontal surface as shown. A massless string is wrapped around an axle of radius r. The string will be pulled horizontally to the right as shown with a force of constant magnitude F. There is sufficient friction (f) between the surface and the yo-yo for the yo-yo to roll without slipping. Assume that the moment of inertia of the yo-yo about its rotation axis is approximatelyI (1/2)mR2. Draw...
A bucket of mass m is hanging from the free end of a rope whose other end is wrapped around a drum (radius R, mass M) that can rotate with negligible friction about a stationary horizontal axis. The drum is not a uniform cylinder and has unknown moment of inertia. When you release the bucket from rest, you find that it has a downward acceleration of magnitude (a). What is the tension in the cable between the drum and the...
Part D (Rotational Dynamics and Oscillations) Problem D1: A disk-shaped pulley has mass M = 4kg and radius R = 0.5cm. It rotates free axis. A block of mass m = 2kg hangs by a string that is tightly wrapped ar the system starts from rest. Moment of inertia of a disk is I = 2 gs by a string that is tightly wrapped around the pulley.
