A stationary bicycle is raised off the ground, and its front wheel (m= 1.99 kg) is rotating at an angular velocity of 25.8 rad/s (see the figure). The front brake is then applied for 1.26 s, and the wheel slows down to 3.03 rad/s. Assume that all the mass of the wheel is concentrated in the rim, the radius of which is 0.330 m. The coefficient of kinetic friction between each brake pad and the rim is Hk = 0.736. What is the magnitude of the normal force that each brake pad applies to the rim? Brake pads 0.33 m SUPPORT

A space station is coast me ted in the shape of a hollow ring of mass 5.00 104 kg. Members of the crew walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius r = 100 m. At rest when constructed, the ring is set rotating about its axis so that the people inside experience an effective free-fall acceleration equal to g. (Sec Fig. P11.29.)
