A demonstration gyroscope wheel is constructed by removing the tire from a bicycle wheel 0.640 mm in diameter, wrapping lead wire around the rim, and taping it in place. The shaft projects 0.210 mm at each side of the wheel, and a woman holds the ends of the shaft in her hands. The mass of the system is 9.50 kgkg ; its entire mass may be assumed to be located at its rim. The shaft is horizontal, and the wheel is spinning about the shaft at 4.90 rev/srev/s .

a)Find the force each hand exerts on the shaft when the shaft is at rest.

b)Find the force each hand exerts on the shaft when the shaft is rotating in a horizontal plane about its center at 5.10×10⁻² rev/srev/s .

c)Find the force each hand exerts on the shaft when the shaft is rotating in a horizontal plane about its center at 0.315 rev/srev/s .

d)At what rate must the shaft rotate in order that it may be supported at one end only?

A demonstration gyroscope wheel is constructed by removing the tire from a bicycle wheel 0.655 m in diameter, wrapping lead wire around the rim, and taping it in place. The shaft projects 0.190 m at each side of the wheel, and a woman holds the ends of the shaft in her hands. The mass of the system is 9.50 kg ; its entire mass may be assumed to be located at its rim. The shaft is horizontal, and the wheel...

. The drive components of a two-speed bicycle are constructed as follows: • The rear wheel has a radius of 50 cm • The front gear has a radius of 10 cm, and is connected to the pedals • There are two rear gears: one with a radius of 5 cm (“high gear”), and one with a radius of 10 cm (“low gear”) • A chain connects the front gear to one of the rear gears; the cyclist can choose...

A steel bicycle wheel (without the rubber tire) is rotating freely with an angular speed of 14.5 rad/s. The temperature of the wheel changes from -142 to 244 °C. No net external torque acts on the wheel, and the mass of the spokes is negligible. What is the angular speed of the wheel at the higher temperature?

Spinning with the bicycle wheel. The person sat on the stool holding the bicycle wheel with the handles vertical and the wheel stopped. Hint the person move counterclockwise. 6. With person feet off the floor (and on the stool’s foot support), the wheel was set to spin rapidly. In which direction is the wheel spinning (CW or CCW)? In which direction was the person spinning (CW or CCW)? 7. The person now stops the wheel. What happens? 8. Explain what...

A bicycle manufacturer buys 5000 tires a year from a distributor. It cost 6 to store one bicycle tire for a year.

A bicycle manufacturer buys 5000 tires a year from a distributor. It cost 6 to store one bicycle tire for a year. To re-order, there is a fixed cost of $24 per shipment plus $11 for each tire. How many times per year should the manufacturer order bicycle tires and in what lot size, to minimize inventory cost?

Consider an old-fashioned bicycle with a small wheel of radius 0.51 m and a large wheel of radius 0.8 m. Suppose the rider starts at rest, accelerates with a constant acceleration for 8 minutes to a velocity of magnitude 24.5 m/s. He maintains his velocity for 9.5 minutes and then decelerates, with constant deceleration, for 7.3 minutes. Find the total angle through which a point on the small wheel has turned.

Consider a bicycle wheel, radius ? with rim of mass ? and axle of mass ?. The masses of the wheel’s thin spokes are so small that we will neglect them. Initially, the wheel is resting on a horizontal surface, and you hold its axle, a hand on each side of the wheel, so that it doesn’t tip over. At time ? = 0? you exert a horizontal force of magnitude ? on the axle so that the wheel begins...
