The energy stored by a fluid mass appears in the form of potential, kinetic and intermolecular energy. The mechanical energy, on the other hand, is usually transmitted by a rotating shaft. Machines using liquid (mainly water, for almost all practical purposes) are termed as hydraulic machines.
The operation of a machine may involve the transformation of chemical, thermal, electrical, or nuclear energy into mechanical energy, or vice versa. All machines have an input, an output, and a transforming or modifying and transmitting device. Machines that receive their input energy from a natural source (such as air currents, moving water ...
Power transmission is an engineering method that engages the machine and the working part of the machine in terms of energy configuration, movement, speed, and motion form. Well, there are different products, including small and large mechanical components, that make the transmission of power possible.

Every machine has to transmit motion because mechanical work is associated with the motion and thus makes use of mechanisms. The mechanism is concerned with the transfer of motion only. Nature. A machine can use one or more than one mechanism to perform the desired function. A mechanism is a single system to transfer or transform motion.
The heart of any hydraulic system is the pump which converts mechanical energy into hydraulic energy. The source of mechanical energy may be an electric motor, the engine, or the operator's muscle. Pumps powered by muscle are called hand pumps. They are used in emergencies as backups for power pumps and for ground checks of the hydraulic system.
