NettetProvided is a sliding constant-velocity universal joint 1 which is provided with six torque-transmitting balls 4 and in which the center of curvature O1 of a spherical outer peripheral surface 11 of a cage 5 and the center of curvature O2 of a spherical inner peripheral surface 12 are offset to opposite sides in an axial direction with respect to a joint center … Nettet7. okt. 2024 · Now the velocity of orbiting depends on the observer. If we take observer at rest in schwarzshild coordinates, this one will measure velocity to be: v = g ϕ ϕ d ϕ − g t t d t = ω g ϕ ϕ − g t t = r s 2 r 3 r 2 1 − r s r = r s 2 ( r − r s). As you can see, this will give you speed of light v = 1 for r = 3 r s / 2.
