Lever a place to stand, and I shall move the Earth with it' is a remark of Archimedes who formally stated the correct mathematical principle of levers (quoted by Pappus of Alexandria). It is assumed that in ancient Egypt, constructors used the lever to move and uplift obelisks weighing more than 100 tons. A lever is a beam connected to ground by a hinge, or pivot, called a fulcrum. The ideal lever does not dissipate or store energy, which means there is no friction in the hinge or bending in the beam. In this case, the power into the lever equals
Front lever difficult. In the 1960s the move was rated B, when the levels of difficulty were A, B, and C. Evidently the athlete's body length is a factor in point scoring as world class gymnasts are shorter now than during the mid 20th century: for example the top American gymnast in 1956 was John Beckner - 6' 1", whereas the 2004 Olympic champion American gymnast, Paul Hamm, is 5' 4". There are many variations for the Front Lever. The easiest is the tuck front lever, then the advanced tuck variation (where the back is kept flat), then the single leg front
