x–ass ir aptuveni paralēla trajekto

x–ass ir aptuveni paralēla trajektorijas s elementam ds, kur kontaktpunkts A apraksta patreizējo trajektoriju, y ir perpendikulārs x. Koordinātu sistēma precīzāk attēlota attēlā 4.1. x un y ir koordinātas punktam A. Tad kosinusi un sinusi leņķim Ф elementam ds veidos x- un y-asis dx/ds un dy/ds un masas centra koordinātes ξ, η, ζ būs:

x-axis is roughly parallel to the trajectory of the s element ds that contact (A) describe the current trajectory is perpendicular to the x, y coordinate system more accurately displayed. in Figure 4.1 x and y are the coordinates of the point of A cosine and sine then the angle element ds Ф ways the x-and y-axes dx and dy/ds/ds and the center of mass coordinates ξ, η, ζ will:

the x-axis is approximately parallel to the path's element ds, where the contact point A describes the current trajectory, y is perpendicular to x. The coordinate system is accurately depicted in Figure 4.1. x and y are the coordinates of point A. Then the cosine of the angle Ф sinuses and ds forms x- and y-axes dx / ds and dy / ds and the center of mass coordinates ξ, η, ζ is:
