The vault is used for vaulting. They hurdle onto a springboard and spring onto
the vault with their hands. The vault used to be almost like the boys pommel
horse, a lot of gymnastics were getting injured so they made the vault longer
and wider. It almost looks like a tongue.
The Balance Beam is used to show your skill and balance while performing
tricks. The balance beam used to not have very much cushioning.

at the 2000 Olympics, gymnasts either rammed into the horse's front end, or
had bad landings after having problems with their hand placements during
push-off. International Gymnastics Federation (FIG) re-evaluated and
changed the apparatus, citing both safety reasons and the desire to
facilitate more impressive acrobatics. Polymers have improved this piece of
equipment by making it longer and wider, also by putting a layer of foam
inside it. This was done for the gymnasts in case they messed up.

Alexander the Great and his Macedonians are said to have practiced mounting and dismounting on a wooden horse. In the fourth century Vegetius describes Roman soldiers practicing on a wooden horse in his “Overview of the Roman Army”. In the early 19th century, when Jahn, regarded as the father of gymnastics, was alive, there were three different kinds of horses on the Hasenheide in Berlin: One very close to reality with a head and a tail, one made of leather without a tail but with an ascending neck and the wooden "Schwingel" (fescue-grass) a word which F.L. Jahn, who detested the use of foreign words in German, had created to avoid the originally French word of Voltegieren. The latter developed into the Olympic apparatus of pommel horse

polymers in it. The Suede makes the
beam softer.
