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 ﬁxed orientation. (b) The period τ of the precession if the spin axis makes an angle of 20 ◦ with respect to the axis of ﬁxed 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...
