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 ...
It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage. Spherical and spatial four-bar linkages also exist and are used in practice. [1] A pumpjack's main mechanism is a four-bar linkage
The horizontal bar, also known as the high bar, is an apparatus used by male gymnasts in artistic gymnastics. It traditionally consists of a cylindrical metal (typically steel ) bar that is rigidly held above and parallel to the floor by a system of cables and stiff vertical supports.
In the current Federation Internationale de Gymnastique (FIG) 2017-2020 Code of Points, a giant is a B (0.2) element on uneven bars for women, [3] and a B (0.2) element on parallel bars and an A (0.1) element on the horizontal bar for men.
According to Itzhak Bars, this analogy conveys the relationship between 1T-physics in 3+1 dimensions (like the physics on the boundaries of the room) and 2T-physics (like physics in the room). The requirement of only gauge-symmetric combinations of 4+2 dimensions demanded by the gauge symmetry is what forces the observers to experience all ...
Boring bar marked B. A boring bar is a tool used in metalworking and woodworking. Boring is a technique used in many aspects of building. Woodworkers have used boring as a form of drilling for centuries. In woodworking, the boring tool is static in size and used to form circular plunge cuts.
These are not considered standard metric sizes, and thus is often referred to as a soft conversion or the "soft metric" size. The US/Imperial bar size system recognizes the use of true metric bar sizes (No. 10, 12, 16, 20, 25, 28, 32, 36, 40, 50 and 60 specifically) which indicates the nominal bar diameter in millimeters, as an "alternate size ...
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.
