In addition to this a cylindrical coordinate system is defined at the center of the workpiece. But if it does get crushed, then some of the side faces might come in contact with the cylindrical block, but since contact isn't defined between them, the side surfaces won't detect contact (and hence penetration will occur). the cylindrical coordinate system is broken by the helical winding of the solenoid, however.

Command to perform the rotation about the global coordinate system goes. There are a total of thirteen orthogonal coordinate systems in which Laplace’s equation is separable, and knowledge of their existence (see Morse and Feshbackl) can be useful for solving problems in potential theory. However, there are many situations where using other coordinate systems (cylindrical or spherical) is more convenient. Set up a system of equations needed to solve each problem.
