Cylindrical coordinate system
Answers
Explanation:
cylindrical coordinate system is a three-dimensional coordinate system that specifies point positions by the distance from a chosen reference axis, the direction from the axis relative to a chosen reference direction, and the distance from a chosen reference plane perpendicular to the axis.
●A cylindrical coordinate system, as shown in Figure 27.3, is used for the analytical analysis. The coordinate axis r, θ, and z denote the radial, circumferential, and axial directions of RTP pipe, respectively. The local material coordinate system of the reinforced tape layers is designated as (L, T, r), where L is the wound direction, T is the direction perpendicular to the aramid wire in plane, and r is the normal direction, same as in the cylindrical coordinate system. The term α is the wound angle of reinforced layer, the angle between L direction and z direction.
