A uniform disk with mass m = 8.88 kg and radius R = 1.3 m lies in the x-y plane and centered at the origin. Three forces act in the +y-direction on the disk: 1) a force 334 N at the edge of the disk on the +x-axis, 2) a force 334 N at the edge of the disk on the –y-axis, and 3) a force 334 N acts at the edge of the disk at an angle θ = 33° above the –x-axis.

A)What is the magnitude of the torque on the disk about the z axis due to F1?
B)What is the magnitude of the torque on the disk about the z axis due to F2?
C)What is the magnitude of the torque on the disk about the z axis due to F3?
D)What is the x-component of the net torque about the z axis on the disk?
E)What is the y-component of the net torque about the z axis on the disk?
F)What is the z-component of the net torque about the z axis on the disk?
G)What is the magnitude of the angular acceleration about the z axis of the disk?
H)If the disk starts from rest, what is the rotational energy of the disk after the forces have been applied for t = 1.8 s?

A uniform solid disk is mounted on an axle n such a way that it is free to rotate about a horizontal axis. The radius of the disk is 0.450 m and its mass is 27.0 kg. As shown in the diagram, two forces F1 = 84.0 N and F2 = 130 N applied to the disk sets the disk rotating with a constant angular acceleration. Assume the axle is frictionless (a) Calculate the magnitude and direction of the net...

A force table applies three forces to a ring in the center of the table. When the forces are balanced, the ring is stationary in the center of the table. The net force equation F1+F2+F3=Fnet becomes F1+F2+F3=0 since a stationary object has no net force acting on it. This equation is true for the cartesian components as well: F1x+F2x+F3x=0 F1y+F2y+F3y=0 For each of the three problems below, calculate the force F3 that balances the table with the given F1 and...

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
