Question

The hubble space telescope is stabilized to within an angle of about of a degree by mean of a series of gyrcopes

Answer 1

Explanation:The Hubble Space Telescope is stabilized to within an angle of about 2-millionths of a degree by means of a series of gyroscopes that spin at 19200 rpm. Although the structure of these gyroscopes is actually quite complex, we can model each of the gyroscopes as a thin-walled cylinder of mass 2 kg and diameter 5 cm, spinning about its central axis. How large a torque would it take to cause these gyroscopes to precess through an angle of 10-6 degree during a five-hour exposure of a galaxy
