WebA cylindrical coordinate system is a system used for directions in \mathbb {R}^3 in which a polar coordinate system is used for the first plane ( Fig 2 and Fig 3 ). The coordinate system directions can be viewed as three vector fields , and such that: with and related to the coordinates and using the polar coordinate system relationships. In mechanics, a cylinder stress is a stress distribution with rotational symmetry; that is, which remains unchanged if the stressed object is rotated about some fixed axis. Cylinder stress patterns include: circumferential stress, or hoop stress, a normal stress in the tangential (azimuth) direction.axial stress, a normal stress … See more Hoop stress The hoop stress is the force over area exerted circumferentially (perpendicular to the axis and the radius of the object) in both directions on every particle in the cylinder wall. It can … See more The first theoretical analysis of the stress in cylinders was developed by the mid-19th century engineer William Fairbairn, assisted by his mathematical analyst Eaton Hodgkinson.
