Unformatted text preview: closely approximated by four uniform spherical shells, each of mass m and radius r . The mass of the connection structure and internal equipment can be neglected. Station designed to rotate about its z-axis once every 4 sec, determine: (a) The number n of complete cycles of precession for each revolution about the z-axis if the plane of rotation deviates only slightly from a xed orientation. (b) The period of the precession if the spin axis makes an angle of 20 with respect to the axis of xed orientation about which the precession occurs. (c) Draw the space/body cones for the condition in part (b). 4. Do problem 18.84 from Beer and Johnston Vector Mechanics for Engineers . 2...
