A 10 kg disk with a hole in its center has a c value about its center of 0.56 has an outer radius of 3.6 meters. A force of 5 Newtons is applied in the -x direction at the edge of the disk directly to the right of its center. Another force of 28 Newtons is applied directly above the center in the -x direction halfway between the center and edge of the disk. Lastly, a force of 15 Newtons is applied on the edge of the disk directly to the left of its center in the +y direction at a distance of 1/4's of the radius of the disk from the center. What is the angular acceleration about the center of the disk in rad/s2? If clockwise, include a negative sign.
A 6 kg disk with a hole in its center has a c value about its center of 0.57 has an outer radius of 3.5 meters. A force of 9 Newtons is applied in the -x direction at the edge of the disk directly to the right of its center. Another force of 34 Newtons is applied directly above the center in the -x direction halfway between the center and edge of the disk. Lastly, a force of 15 Newtons...
A solid disk with a c value of 1/2, mass of 3 kg, and radius of 1.5 meters lies on a horizontally (so the normal force and weight can be ignored). A force of 9 Newtons is applied 0.22 meters directly to the right of the center in the +x direction, a force of 24 Newtons is applied at 0.81 meters directly below of the center in the +x direction and a force of 8 Newtons is applied at the...

A 8 kg disk with a radius of 1 meters has several forces applied to it as shown in the sketch. F1 is 41 N and is applied at the edge of the disk, F2 is 7 N is applied at 1/4 the radius from the center of the disk, F3 is 5 N is applied at 3/4 the radius from the center, F4is 29 N is applied at the edge of the disk, and, lastly, F5 is 16 N...
Question 7 8 pts A disk is rotating at 21 rad/s counter-clockwise about its center and a constant angular acceleration of 4 rad/s? is applied to it clockwise. After 0.69 seconds, what is its rotational kinetic energy about its center if c 1/2, the mass of the disk is 4 kg, and its radius is 0.74 meters? Answer in Joules.
A disk with a mass of 15 kg is spinning about its center with a constant angular acceleration applied to it. Its c value is 1/2 about its center and it is initally spinning at 5 rad/s clockwise. If the disk stops spinning in a time of 1.5 s, how many revolutions does the disk make until it stops? 1.79 rev. 3.75 rev. 11.25 rex 0.60 rev. MacBook Pro $ % 5 & 7 8 E R T Y F...
Chapter 5, Problem 5/144 The disk rolls without slipping on the horizontal surface. If the disk has a clockwise angular velocity of wo-21 rad/s and a counterclockwise angular acceleration of 3.6 rad/s2 determine the veloclty and acceleratlon of pln A relatlve to the slotted member BC and the angular velocity and angular acceleratlon of BC. The value of r is 225 mm. Neglect the distance from the center of pin A to the edge of the disk. The relative velocity...
A uniform disk of radius 0.455 m0.455 m and unknown mass is constrained to rotate about a perpendicular axis through its center. A ring with the same mass as the disk is attached around the disk's rim. A tangential force of 0.237 N0.237 N applied at the rim causes an angular acceleration of 0.129 rad/s2.0.129 rad/s2. Find the mass of the disk.Why is this wrong? A uniform disk of radius 0.455 m and unknown mass is constrained to rotate about...
A disk is originally spinning about its center at 4.8 rad/s clockwise. It makes 3.6 revolutions before it is stopped. If under a constant angular acceleration, how long does it take to stop in seconds?
A disk is initially rotating (about its center) at 48 rad/s counter-clockwise. After a constant angular acceleration is applied to it for 2.2 seconds, it is rotating at 9 rad/s counter-clockwise. How many revolutions does the disk make in that time
