#2. [Swinging Disk] A uniform circular disk of mass M and radius R is set swinging side-to-side about a frictionless pivot P at its edge (a) What is the disk's moment of inertia about the pivot? (b) Write an expression for the net torque acting on the disk about the pivot when the disk is displaced to the right by angle θ CM (c) Write Newton's 2nd Law for Rotation for the disk when it is displaced as shown. Be...
Thanks so much for the help! Please show all work. A uniform solid disk with radius 9 cm has mass 0.5 kg (moment of inertia I = ½MR2). A constant force 12 N is applied as shown. At the instant shown, the angular velocity of the disk is 40 radians/s in the −z direction (where +x is to the right, +y is up, and +z is out of the page, toward you). The length of the string d is 13...

Problem 4 1. An object with a mass m is attached to the free end of a light string wrapped around a reel of radius R and mass M. The reel is a solid disk, free to rotate in a vertical plane about the horizontal axis passing through its center (of mass) as shown in the figure below. The suspended object is released from rest h m above the floor. The entire system is...
A uniform disk with mass 38.8 kg and radius 0.200 m is pivoted at its center about a horizontal, frictionless axle that is stationary. The disk is initially at rest, and then a constant force 25.0 N is applied tangent to the rim of the disk. a)What is the magnitude v of the tangential velocity of a point on the rim of the disk after the disk has turned through 0.170 revolution? b)What is the magnitude a of the resultant...
A uniform disk with mass m = 8.66 kg and radius R = 1.38 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 301 N at the edge of the disk on the +x-axis, 2) a force 301 N at the edge of the disk on the –y-axis, and 3) a force 301 N acts at the edge of the disk at an angle θ =...
A uniform disk with mass m = 9.31 kg and radius R = 1.43 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 349 N at the edge of the disk on the +x-axis, 2) a force 349 N at the edge of the disk on the –y-axis, and 3) a force 349 N acts at the edge of the disk at an angle θ =...
A uniform disk with mass m = 9.04 kg and radius R = 1.35 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 309 N at the edge of the disk on the +x-axis, 2) a force 309 N at the edge of the disk on the –y-axis, and 3) a force 309 N acts at the edge of the disk at an angle θ =...
A uniform disk with mass 35.2 kg and radius 0.230 mis pivoted at its center about a horizontal, frictionless axle that is stationary. The disk is initially at rest, and then a constant force 29.5 N is applied tangent to the rim of the disk. What is the magnitude v of the tangential velocity of a point on the rim of the disk after the disk has turned through 0.210 revolution? What is the magnitude a of the resultant acceleration...
A uniform disk with mass m = 9.07 kg and radius R = 1.36 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 313 N at the edge of the disk on the +x-axis, 2) a force 313 N at the edge of the disk on the –y-axis, and 3) a force 313 N acts at the edge of the disk at an angle θ =...
A uniform disk with mass m = 8.55 kg and radius R = 1.35 m lies in the xy plane and centered at the origin. Three forces act on the disk in the +y-direction (see figure below): (1) a force F1 = 335 N at the edge of the disk on the +x-axis, (2) a force F2 = 335 N at the edge of the disk on the ?y-axis, and (3) a force F3 = 335 N at the edge...
