Lever is obtained as which is the mechanical advantage of the lever. This equation shows that if the distance "a" from the fulcrum to the point "A" where the input force is applied is greater than the distance "b" from fulcrum to the point "B" where the output force is applied, then the lever amplifies the input force. If the opposite is true that the distance from the fulcrum to the input point "A" is less than from the fulcrum to the output point "B", then the lever reduces the magnitude of the input force.

Mark A. Lever faculty of ETH Zurich. Lever is a member of the Deep Life Scientific Steering Committee and Synthesis Group 2019 for the Deep Carbon Observatory and is an associate editor for "Frontiers in Microbiology". In his research, Dr. Lever investigates factors that determine the presence, abundance, community composition, and metabolism of microorganisms in aquatic sediments and in Earth's crust. In 2013 he discovered that microbes survive deep in the crust by living off of chemical energy in the “dark biosphere.” His work has a special focus on the burial, remineralization, and synthesis of organic matter in aquatic sediments and in Earth’s
