Cylindrical velocity
A cylindrical coordinate system is a three-dimensional coordinate system that specifies point positions by the distance from a chosen reference axis (axis L in the image opposite), the direction from the axis relative to a chosen reference direction (axis A), and the distance from a chosen reference plane perpendicular to the axis (plane containing the purple section). The latter distance is given a… WebJul 20, 2024 · The velocity is given by →v(t) = Rdθ(t) dt ˆθ(t) = R(A − 3Bt2)ˆθ(t) The angular velocity is zero at time t = t1 when A − 3Bt2 1 = 0 ⇒ t1 = √A / 3B For t < t1, dθ ( t) dt = A − 3Bt2 1 > 0 hence →ω(t) points in the positive ˆk -direction. For t > t1, dθ ( t) dt = A − 3Bt2 …
