A disk of radius 0.46 m and moment of inertia 2.1 kg·m2 is mountedon a nearly frictionless axle. A string is wrapped tightly aroundthe disk, and you pull on the string with a constant force of 34N.



What is the magnitude of the torque?
torque = 15.64 N·m

After a short time the disk has reached an angular speed of 6radians/s, rotating clockwise. What is the angular speed 0.85seconds later?
angular speed = ???? radians/s

A string is wrapped around a uniform disk of mass M = 2.5 kg andradius R = 0.04 m. (Recall that the moment of inertia of a uniformdisk is (1/2)MR^2.) Attached to the disk are four low-mass rods ofradius b = 0.07 m, each with a small mass m = 0.5 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 = 25 N. At theinstant when the center of the disk has moved a distance d = 0.035m, a length w = 0.021 m of string has unwound off the disk.



(a) At this instant, what is the speed of the center of theapparatus?
v = ___ m/s

(b) At this instant, what is the angular speed of theapparatus?
omega1 = _____ radians/s

(c) You keep pulling with constant force 25 N for an additional0.040 s. Now what is the angular speed of the apparatus?
omega2 = _____ radians/s

A string is wrapped around auniform disk of mass M = 1.2 kg and radius R = 0.07 m. (Recall thatthe moment of inertia of a uniform disk is (1/2)MR2.) Attached tothe disk are four low-mass rods of radius b = 0.11 m, each with asmall mass m = 0.5 kg at the end. The device is initially at reston a nearly frictionless surface. Then you pull the string with aconstant force F = 29 N. At the instant when the center of the diskhas moved a distance d = 0.039 m, a length w = 0.023 m of stringhas unwound off the disk.





(a) At this instant, what is the speed of the center of theapparatus?

(b) At this instant, what is the angular speed of theapparatus?
w1 = ? radians/s

(c) You keep pulling with constant force 29 N for an additional0.022 s. Now what is the angular speed of the apparatus?

an irregularly shaped plastic plate with uniform thickness and density (mass per unit volume) is to be rotated around an axle that is perpendicular to the plate face and through point O. The rotational inertia of the plate about that axle is measured with the following method. A circular disk of mass 0.53 kg and radius 1.6 cm is glued to the plate, with its center aligned with point O (Figure b). A string is wrapped around the edge of the disk the way a string is wrapped around a top. Then the string is pulled for 5.2 s. As a result, the disk and plate are rotated by a constant force of 0.41 N that is applied by the string tangentially to the edge of the disk. The resulting angular speed is 110 rad/s. What is the rotational inertia of the plate about the axle?
