Consider the two (combined mass=8.0kg, total width=1.8m) hands
and arms of a skater preparing to spin as one slender rod pivoting
through its center, and when wrapped as a thin-walled hollow
cylinder of radius 25cm. The moment of inertia of THE REST of his
body is 0.40kg.m2. His initial angular speed is 0.40rev/s, what is
his final angular speed?

The outstretched hands and arms of a figure skater preparing for
a spin can be considered a slender rod pivoting about an axis
through its center ( Ibar = 1 12 mℓ2 where ℓ is the length of the
bar ). When the skater's hands and arms are brought in and wrapped
around their body to execute the spin, the hands and arms can be
considered a thin-walled hollow cylinder. The hands and arms have a
combined mass 10 kg....

Part A The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center. (See the figure below (Figure 1).) When the skater's hands and arms are brought in and wrapped around his body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. His hands and arms have a combined mass of 8.50 kg. When outstretched, they span 1.80 m;...

The 160 lb ice skater with arms extended horizontally spins about a vertical axis with a rotational speed of 1 rev/sec. Estimate his rotational speed if he fully retracts his arms, bringing his hands very close to the centerline of his body. As a reasonable approximation, model the extended arms as uniform slender rods, each of which is 27 in. long and weighs 13 lb. Model the torso as a solid 134-lb cylinder 13 in. in diameter. Treat the man...
