The key performance factor of BRAČA-SPORT® oar is the revolutionary “Mechanical Energy” concept – is the shafts ability to store elastic potential energy during the first part of drive and release it during and after the midrange in the controlled mode, enabling the maximum velocity of boat.
The mechanical energy of an object can be the result of its motion (kinetic energy) and/or the result of its stored energy of position (potential energy). There are two forms of potential energy: gravitational potential energy and elastic potential energy. The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy. This sum is simply referred to as the total mechanical energy (TME).
