A Fresnel Lens Without The Pain

SOLVED:An experimental Fresnel-lens solar-energy concentrator can rotate about the horizontal axis A B that passes through its mass center G. It is supported at A and B by a steel framework that can rotate about the vertical y axis. The concentrator has a mass of 30 Mg, a radius of gyration of 12  m about its axis of symmetry C D, and a radius of gyration of 10  m about any transverse axis through G. Knowing that the angular velocities ω1 and ω2 have constant magnitudes equal to 0.20 rad / s and
