Find the exact values of two possible rates of precession

Reference no: EM131391289

A high-speed photographic record shows that a certain projectile Problems was fired with a horizontal velocity v of 600 m/s and with its axis of symmetry forming an angle ß = 3° with the horizontal. The rate of spin c? of the projectile was 6000 rpm, and the atmospheric drag was equivalent to a force D of 120 N acting at the center of pressure CP located at a distance c = 150 mm from G.

(a) Knowing that the projectile has a mass of 20 kg and a radius of gyration of 50 mm with respect to its axis of symmetry, determine its approximate rate of steady precession.

(b) If it is further known that the radius of gyration of the projectile with respect to a transverse axis through G is 200 mm, determine the exact values of the two possible rates of precession.
