A pneumatic exercise machine or pneumatic exercise equipment is an exercise machine or equipment for physical exercise whose function is based on pneumatics, as opposed to or in combination with for example cables or hydraulics.
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ratchet is also used informally to refer to a ratcheting socket wrench.
An exercise class using exercise balls A wide range of exercises can be performed with an exercise ball.. An exercise ball is a ball constructed of soft elastic, typically in 5 diameters of 10 cm increments, from 35 to 85 cm (14 to 33 in), and filled with air.
In bodybuilding and weight training, using drop sets (aka dropsets, descending sets, strip sets, the multi-poundage system the stripping method, triple-drops, down the rack, or running the rack) [1] is a technique for continuing an exercise with a lower weight once muscle failure has been achieved at a higher weight.
Aquatic timing systems are designed to automate the process of timing, judging, and scoring in competitive swimming and other aquatic sports, including diving, water polo, and synchronized swimming. [1] These systems are also used in the training of athletes, and many add-on products have been developed to assist with this process. [2]
The Swiss Gymnastics Federation (French: Fédération Suisse de Gymnastique) is the governing body of gymnastics in Switzerland. Based in Aarau , it is a member of the Swiss Olympic Association . Founded in 1985, by merging the Federal Gymnastics Society (founded 1832) and the Swiss Association for Women's Gymnastics (founded 1908), [ 1 ] the ...
Schematic figure of a Brownian ratchet. In the philosophy of thermal and statistical physics, the Brownian ratchet or Feynman–Smoluchowski ratchet is an apparent perpetual motion machine of the second kind (converting thermal energy into mechanical work), first analysed in 1912 as a thought experiment by Polish physicist Marian Smoluchowski.

The main differences between the M240B and M240G is the Picatinny rail system, hydraulic buffer inside of the butt stock to reduce the amount of recoil felt by the gunner, and the number of gas settings on the gas regulator plug. The M240G has three gas settings, allowing the machine gun to have a fire rate between 650 and 750 rounds per minute ...
