You have your bicycle upside-down for repairs. The front wheel is free to rotate and is perfectly balanced except for the 34 g valve stem.

1.If the valve stem is 34 cm from the rotation axis and is located 24 ∘ below the horizontal, what is the resulting torque about the wheel's axis?

Answer #1

torque will be due to the vertical component of force

Torque = F*r

= 0.034*9.8*sin 24 * 0.34

= 0.046 N-m

so the resulting torque about the whell's axis is 0.046 N-m

    A bicycle wheel has four firecrackers attached to it on opposite ends of the wheel's diameter, as shown in the figure to the right. When the firecrackers are lit, they release heated gas away from their front ends. The bicycle wheel is pivoted against a wall by its center of mass and is free to spin. a. Which way will the bicycle wheel spin when the firecrackers are lit? Explain using the torque right hand rule. b. What is the...

    A student holds a spinning bicycle wheel while sitting motionless on a stool that is free to rotate about a vertical axis through its center (see the figure below). The wheel spins with an angular speed of 16.1 rad/s and its initial angular momentum is directed up. The wheel's moment of inertia is 0.110 kg · m2 and the moment of inertia for the student plus stool is 3.30 kg · m2. (a) Find the student's final angular speed (in...

    Consider a bicycle wheel of mass M and radius R that sits on a flat, level surface, such that the surface is tangent to the wheel. One end of a spring (spring constant, k) is attached to bicycle wheel's hub, and the other end is fixed to a vertical wall. The spring is horizontal. There is sufficient friction to prevent the wheel from sliding at the point of contact with the surface. When the center of the wheel is directly...

    Up A #4. [Gyroscope Wheel] A rubber wheel on a steel rim spins freely on a horizontal axle that is suspended by a fixed pivot at point P. When the wheel spins at a rate of 4.00 rev / s, it precesses smoothly about point Pin a horizontal plane with a period of 3.50 s. The wheel's outer radius is 15.0 cm, and it's total mass is measured to be 1.12 kg, 60% of this being the spinning wheel and...
