Lever fulcrum to where the output force is applied (point "B"), then the lever amplifies the input force. On the other hand, if the distance "a" from the fulcrum to the input force is less than the distance "b" from the fulcrum to the output force, then the lever reduces the input force. The use of velocity in the static analysis of a lever is an application of the principle of virtual work. A lever is modeled as a rigid bar connected to a ground frame by a hinged joint called a fulcrum. The lever is operated by applying an input
Front lever lever, straddle front lever, and finally on to the full front lever. At any stage of learning the skill the gymnast may perform pull-ups in the front lever position of their choice. A front lever held with just one arm. The body is often turned sideways in this variation The body is kept horizontal while the gymnast performs a pullup. In this variation the performer leans forward from the lever position, bringing the legs down and arms up until he/she reaches the top of a regular pullup. From here they lean back again, straightening the arms and returning to the
