A 25-kg wheel has a radius of 40 cm and turns freely on a horizontal axis. The radius of gyration of the wheel is 30 cm. A 1.2-kg mass hangs at the end of a cord that is wound around the rim of the wheel. The mass falls and causes the wheel to rotate. Find the acceleration of the falling mass and the tension in the cord, whose mass can be ignored.

A light string is wrapped
around the outside of a 2.0-kg-wheel whose radius is 75 cm. The
wheel has a frictionless axel that allows it to rotate but prevents
its center of mass from moving. Assume the moment of inertia of the
wheel is the same as that of a point particle of equal mass at the
same radius from the axel. The string is then attached to a 3.0-kg
hanging mass that is released from rest. While the mass...

A constant-density cylinder of mass 0.5 kg and radius 4 cm can rotate freely about an axis through its center. It has thread wound around an attached axle of radius 0.5 cm that also runs through its center (Fig. as shown) The thread is attached to a mass of 1 kg, which slides down an inclined plane of angle ф-300 with an acceleration of 0.1 m/s. a) Draw a free body diagram of the system by PROBLEM 4: (12pts) R....

3. The device shown below consists of a square loop of steady current in a magnetic field, attached to an axle which turns a wheel. Around the wheel is wound a (massless) string (the string comes down over the front of the wheel as shown in the diagram), from which hangs a mass. The mass rises and falls such that it is at rest when the plane of the loop is vertical, and is again at rest when the plane...

A 12.0 kg object is attached to a cord that is wrapped around a
wheel of radius 10.0 cm. The acceleration of the object down the
frictionless incline is measured to be 2.00 m/s2. Assuming the axis
of the wheel to be frictionless, determine a) the tension in the
rope, b) the moment of inertia of the wheel, and c) the angular
speed of the wheel 2.00 s after it begins rotating, starting from
rest.

A cord s wrapped around the rim of a solid uniform wheel 0.22 m in radius and of mass 8.60 kg . A steady horizontal pull of 50.0 N to the right is exerted on the cord, pulling it off tangentially from the wheel.

A potter's wheel having a radius of 0.500 m and mass 45.0 kg is rotating freely at 50.0 rev/min in a clockwise direction. The potter can stop the wheel by pressing a wet rag against the outside rim of the wheel and exerting a radially inward force of 70.0 N. Since this force is in the radial direction, it alone cannot cause the wheel to slow its spinning. What can happen, however, is that a normal force can result from...
