A 8.45 kg uniform disk with a radius of 14.1 cm is wrapped with a massless...
A string is wrapped around a uniform disk of mass M = 2.2 kg and radius R = 0.1 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR2.) Attached to the disk are four low-mass rods of radius b = 0.13 m, each with a small mass m = 0.7 kg at the end. The device is initially at rest on a nearly frictionless surface. Then you pull the string with a constant force F...
A uniform disk of radius 0.2 m and mass m = 16 kg is mounted on a nearly frictionless axle. A string is wrapped tightly around the disk and pulled with a constant force of F = 1 N. After a while the disk has reached an angular speed of ω0 = 2.3 rad/s. What is its angular speed 1.5 s later?
A uniform cylinder of mass 3.0 kg and radius 10.0 cm
has a rope wrapped around its edge; a tension of 5.0 N
is
exerted on the rope. The cylinder rotates at a
constantly
increasing rate, starting from rest.
10DCH 1. A uniform cylinder of mass 3.0 kg and radius 10.0 cm has a rope wrapped around its edge; a tension of 5.0 N is exerted on the rope. The cylinder rotates at a constantly increasing rate, starting from rest....
A string is wrapped around a disk of mass m = 1.8 kg and radius R = 0.10 m. Starting from rest, you pull the string with a constant force F = 7 N along a nearly frictionless surface. At the instant when the center of the disk has moved a distance x = 0.14 m, your hand has moved a distance of d = 0.33 m. Two pucks, one pulled from the center, the other by a string wrapped...
A uniform disk has a radius of 30 cm and a mass of 60 kg it is suspended from the ceiling by two strings the left string is attached to a disk at a point aong a horizontal diameter 5 cm from the left edge and the right string is attached to the disk at a point along the same horizontal diameter at a very right edge if the right edge of the disk cut what will be the initial...
A string is wrapped around a uniform solid cylinder of radius
4.60 cm, as shown in the figure. The cylinder can rotate freely
about its axis. The loose end of the string is attached to a block.
The block has mass 19.6 kg, and the cylinder has mass 12.3
kg.
a) Find the magnitude α of the angular acceleration of the cylinder
as the block descends.
b)What is the acceleration of the block?
c)What is the tension in the string?
A rope is wrapped around the rim of a large uniform solid disk of mass 305 kg and radius 2.10 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest, what is its angular speed in rev/s at the end of 2.65 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 225 kg and radius 2.50 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest, what is its angular speed in rev/s at the end of 1.65 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 295 kg and radius 2.40 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest what is its angular speed in rev/s at the end of 1.95 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 315 kg and radius 1.60 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest what is its angular speed in rev/s at the end of 2.95 s?
