A uniform solid disk of radius R and mass M is free to rotate on a frictionless .... bar with length d = 1.4 m and mass M. The bar is initially at rest but can rotate freely ... gum is a point particle and assume that the pivot is frictionless. ...

a uniform horizontal circular disc of mass M and radius R can freely rotate about a vertical axle passing through its centre. A particle of mass m is intially placed near the centre of the disc in a smooth grove made along the radius of the disc.An intial angular velocity w 0 is imparted to the disc. find the angular velocity of the disc,when the particle reaches the other end of the grove.A uniform horizontal circular disc of mass M and radius R can freely rotate about a vertical axle passing through its centre. A particle of mass m is placed near the centre of the disc in a smooth groove made along the radius of the disc as shown. An initial angular velocity ω 2 is imparted to the disc. Find the angular velocity of the disc, when the particle reaches the other end of the groove.

65. A uniform disk, such as a record turntable, turn at 7.0rev/s around a frictionless spindle. A non-rotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk. They then both turn around the spindle with their centers superposed, Fig. 8-46.Figure shows a rigid assembly of a thin hoop (of mass m and radius R = 0.150 m) and a thin radial rod (of mass m and length L = 2.00R). The assembly is upright, but if we give it a slight nudge, it will rotate around a horizontal axis in the plane of the rod and hoop, through the lower end of Hoop the rod.a uniform disc of mass m and radius r is pivoted at a point P on its rim and is free to rotate in the vertical plane.the centre C of disc is initially in horizontal position with respect to P.if it is released fromn this position ,what will be its angular acceleration when the line PC is inclined to the horizontal at an angle theta?The pulley shown above has a mass of 1.00 kg and radius R = 30.0 cm, and can be treated as a uniform solid disk that can rotate about its center. The block (which has a mass of m = 500 g) hanging from the string wrapped around the pulley is then released from rest. Use g = 10 m/s2.10.39 A block of mass m 1 = 2.00 kg and one of mass m 2 = 6.00 kg are connected by a massless string over a pulley that is in the shape of a disk having radius R = 0.25 m and mass M = 10.0 kg. In addition, the blocks are allowed to move on a fixed block-wedge of angle theta = 30.0 o as in Figure P10.29.Figure 11.7 shows a uniform disk with mass M and radius R. The disk is mounted on a fixed axle. A block with mass m hangs from a light cord that is wrapped around the rim of the disk. Find the acceleration of the falling block, the angular acceleration of the disk, and the tension of the cord. Figure 11.7.

(a) A uniform, solid disk of radius R and mass Mis free to rotate on a frictionless pivot through a point on its rim (Fig. PI 0.49). If the disk is released from rest in the position shown by the blue circle, what is the speed of its center of mass when the disk reaches the position in- dicated by the dashed circle? (b) What is the speed ofA uniform solid disk of mass m = 2.94 kg and radius r = 0.200 m rotates about a xed axis perpendicular to its face with angular frequency 6.02 rad/s. • a)Calculate the magnitude of the angular momentum of the disk when the axis of rotation passes through its center of mass. • b)What is the magnitude of the angular momentum when theA uniform disk of mass 500 kg and radius 0.25 m is mounted on frictionless bearings so it can rotate freely around a vertical axis through its center (see the following figure).
