The bar is a metric unit of pressure defined as 100,000 Pa (100 kPa), though not part of the International System of Units (SI). A pressure of 1 bar is slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar).
The uneven bars or asymmetric bars is an artistic gymnastics apparatus. It is made of a steel frame. The bars are made of fiberglass with wood coating, or less commonly wood. [1] The English abbreviation for the event in gymnastics scoring is UB or AB, and the apparatus and event are often referred to simply as "bars". The bars are placed at ...
10-inch and 100-millimetre sine bars. In the U.S., 5-inch sine bars are the most common size. [1] Angles are measured using a sine bar with the help of gauge blocks and a dial gauge or a spirit level. The aim of a measurement is to measure the surface on which the dial gauge or spirit level is placed horizontally.
The bars are composed of wood or other material, with an outer wood coating. [2] The vertical members of the supporting framework are adjustable so the height of the bars above the floor and distance between the bars can be set optimally for each gymnast. [3]
The fermi is a unit of distance used in nuclear physics equal to 1 fm. [9] The angstrom (symbol Å) is a unit of distance used in chemistry and atomic physics equal to 100 pm. The micron (μ) is a unit of distance equal to one micrometre (1 μm). The basic module (M) is a unit of distance equal to one hundred millimetres (100 mm).

Each grip is commonly used for a particular set of skills. When gymnasts compete on the horizontal bar, they are often required by the Code of Points to use specific grips. The overhand grip, or regular grip, is the standard grip used for the horizontal bar. On the overhand grip, the hands circle the bar with the backs of the hands facing the ...
