The effects of nutation and pseudoregular precession in misaligned binary systems are studied and applied to SS 433. In the context of slaved disk type models, geometrical considerations alone predict that beam angles should oscillate with a period of 6.06 d, as observed by Newsom and Collins (1981) and by Wagner et al. (1981). The predicted angular amplitudes and phases are compared with the ones reported by Newsom and Collins. These angular oscillations, together with the 164 d precession period, predict a photometric oscillation of 6.30 d, as reported by Mazeh et al. (1981). This photometric period is explained by the nutating disk rim periodically obscuring the central regions of the disk in a manner analogous to the X-ray absorption dips seen in Her X-1. This period should thus be most pronounced during phases when the rim is viewed nearly edge-on.
