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 sp
ins at a rate of 4.00 rev/s, it precesses smoothly about point P in a horizontal plane with a period of 3.50 s. The wheel's outer radius is 15.0 cm, and its total mass is measured to be 1.12 kg, 60% of this being the spinning wheel, and 40% its axle assembly. The wheel and its axle are both symmetric about the middle of the wheel, and the pivot point P is 4.70 cm from the wheel's middle. a. its axle considered as a body.
b. What is the direction of the net torque on the wheel about the pivot point P?
c. If the wheel is spinning counterclockwise (0) as seen from point B on the wheel's axle, what is the direction of its spin angular momentum referenced to the diagram?
d. As seen from point A above the pivot, which way is the wheel precessing (C or O)? Please give your reasoning.
e. Using this information, determine the moment of inertia I of the wheel about its axle. Please be sure your work is clear.
Unique Selling Proposition (USP) is the distinguishing feature that makes one product or business better than its competitor in the market. Jen has developed a competitive advantage of the new sunglasses brand making the company to sell their products. This is an example of USP.
