If you lift the front wheel of a poorly maintained bicycle off the ground and then start it spinning at 0.66 rev/s, friction in the bearings causes the wheel to stop in just 13 s. If the moment of inertia of the wheel about its axle is 0.33 kg⋅m2, what is the magnitude of the frictional torque?
A bicycle wheel of mass M and radius R is placed on a vertical axle and...
A bicycle wheel of mass M and radius R is placed on a vertical axle and is able to rotate without friction. A dart of mass, m is fired toward the wheel with an initial velocity v(o). The dart strikes the wheel and sticks in the tire. The moment of inertia of the wheel is I=mr^2. What is the initial angular momentum of the dart with respect to the center of the wheel? What is the angular velocity of the...

A bicycle wheel of mass M (assumed to be concentrated at its
rim) and radius R is mounted horizontally so it may turn without friction on a vertical axle. A dart of mass
mo is thrown with velocity vo as shown above and sticks in the tire. a. If the wheel is initially at rest, find its angular velocity co after the dart strikes b. In terms of the given quantities, determine the ratio: final kinetic energy of the system initial kinetic energy of...

In a demonstration, a bicycle wheel with moment of inertia 0.37 kg.m2 is spun up to 14 rad/s, rotating about a vertical axis. A student holds the wheel while sitting on a rotatable stool. The student and the stool are initially stationary and have a moment of inertia equal to l 3.60 kg.m2. If the student turns the bicycle wheel over so its axis point in the opposite direction, with what angular velocity will the student and stool rotate? Assume...

Consider a bicycle wheel that initially is not rotating. A block of mass m is attached to the wheel via a string and is allowed to fall a distance h. Assume that the wheel has a moment of inertia I about its rotation axis Now consider the case that the string tied to the block is wrapped around a smaller inside axle of the wheel of radius rB as shown in (Figure 2) . Find ωB, the angular speed of...
A potter's wheel having a radius of 0.500 m and mass 45.0 kg is rotating freely...
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...

A person sits on a frictionless stool that is free to rotate but is initially at rest. The person is holding a bicycle wheel (I = 3 kg*m2) that is rotating at 8 rev/s in the clockwise direction as viewed from above, and the moment of inertia of the person-wheel-stool system is 9 kg*m2. For this problem, all answers involving a rotational component will be expressed in revolutions rather than radians. 1. What is direction of the angular momentum of...
