Cylindrical Section
They are in general curves and are special types of plane sections.
Cylindrical section. A cylindric section is the intersection of a plane with a right circular cylinder. We ll start off with the cylindrical coordinate system. A cylindric section is the intersection of a cylinder s surface with a plane.
Cylindrical coordinates as with two dimensional space the standard x y z x y z coordinate system is called the cartesian coordinate system. A hydrocyclone is constructed of a cylindrical section joining to a conical section. If there are two cutting planes one perpendicular to the axis of the cylinder and the other titled with respect to it the resulting solid is known as a cylindrical wedge.
The cylindric section by a plane that contains two elements of a cylinder is a parallelogram. Such a cylindric section of a right cylinder is a rectangle.
