A cylindrical coordinate system is used for cylindrical symmetrical problems (examples, cables, machine rotor etc.). This system does not have axes like cartesian coordinate system.
Any point P ( r, Θ ,z ) is represented by the intersection of three mutually orthogonal surfaces.
where r the radius of a cylinder.
Θ is the azimuthal angle and
z is the constant plane is same as in cartesian coordinate system.
Representation of unit vectors in cylindrical coordinate system:
The three unit vectors can be represented as ri, Θj, zk. Continue reading “cylindrical coordinate system and its transformation to cartesian or rectangular coordinate system”
