A torque of 12.1 N. m is applied to a solid, uniform disk of radius 0.51 m. If the disk accelerates at 1.60 rad/s^2, what is the mass of the disk?

A uniform disk of radius 0.489 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 0.211 N applied at the rim causes an angular acceleration of 0.115 rad/s2. Find the mass of the disk.

A uniform disk of radius 0.521 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 0.201 N applied at the rim causes an angular acceleration of 0.107 rad/s2. Find the mass of the disk.

A 2.00-m-long, 500 kg steel uniform beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 70 kg construction worker stands at the far end of the beam. What is the magnitude of the torque about the bolt due to the worker and the weight of the beam?

A torque of 35.6 N · m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 9.9 rad/s. After 5.80 s the directed force is removed, and the wheel comes to rest 59.8 s later.

A small grinding wheel has a moment of inertia of 4.0 x 10-5 kg ⋅ m2. What net torque must be applied to the wheel for its angular acceleration to be 150 rad/s2?

A torque of 12 N*m is applied to a solid uniform disk with a radius of .5 meters that causes the disk to accelerate at 5.7 rad/s^2. What is the mass of the disk?

A steel disc with a mass of 1.505 kg and a diameter of 8.00 cm is rotating with angular speed 4.75 rad/s. A second, aluminum disc of the same diameter but with mass 527 g and rotating with angular speed -0.07 rad/s is dropped on to the steel disc and both come to a common angular speed. What is this final angular speed?

If a  torque of 20 N.m is applied to a wheel (I wheel = m R 2 ) radius 0.60 m. If the wheel accelerates at a rate of 2 rad/s 2, what is the mass of the disk?

An 80 cm long thin rod whose axis of rotation is in the center has a mass of 0.142 kg. A 2.5 N force is applied at one end perpendicularly, while a second 1.5 N force is applied 10 cm from the opposite end. Both forces are applied in the same direction. (a) Find the angular acceleration. (b) Determine the force needed for the rod to be in equilibrium, if the third force is applied at a 300 angle halfway between the 2.5 N and the axis of rotation.
