Pneumatics (From Greek: πνεύμα) is a branch of engineering that makes use of gas or pressurized air.

A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a plumbing system), containing pressure, or excluding contamination.

The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets.

Hydraulics (From Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids or fluids.

At a very basic level, hydraulics is the liquid version of pneumatics.

Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids.

In fluid power, hydraulics are used for the generation, control, and transmission of power by the use of pressurized liquids.

Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry, pumps.

The principles of hydraulics are in use naturally in the human body within the heart and the male erection.

Motor oil, engine oil, or engine lubricant is any of various substances (comprising oil enhanced with additives, for example extreme pressure additives) are often used for lubrication of internal combustion engines.

The main function of motor oil is to reduce wear on moving parts; it also cleans moving parts from the sludge, inhibits corrosion, improves sealing, and cools the engine by carrying heat away from moving parts.

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.

The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.

Most bearings facilitate the desired motion by minimizing friction.

Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.
