In physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar one-dimensional continuous object, or by each end of a rod, truss member, or similar three-dimensional object.

A tension control bolt is a heavy duty bolt used in steel frame construction.

A tension-leg platform is a vertically moored floating structure normally used for the offshore production of oil or gas, and is particularly suited for water depths greater than 300 metres (about 1000 ft) and less than 1500 metres (about 4900 ft). Use of tension-leg platforms has also been proposed for wind turbines.

Any structure used for the assembly, processing, embarking, or disembarking of cargo.

A person appointed by the terminal or other facility where the ship is being loaded or unloaded.

LAMNALCO SANA’A is the high-performance ASD tug built to the RAstar design developed by Robert Allan Ltd., naval architects of Vancouver, B.C.

Ternary fission is a comparatively rare type of nuclear fission in which three charged products are produced rather than two.

Sometimes used informally to refer to any area of water over which a state has jurisdiction usually 12nm from the coast.

A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891.

A valve from which a sample can be drawn for testing or visual examination, e.g. salinometer cock on a boiler or test cock on an oily water separator.

Tetrafluoromethane (Carbon tetrafluoride) is a useful refrigerant but also a potent greenhouse gas.

The Texas Interconnection is an alternating current (AC) power grid – a wide area synchronous grid – that covers most of the state of Texas.

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes, distinguishing two kinds of transfer of energy, as heat and as thermodynamic work, and relating them to a function of a body's state, called Internal energy.

The Geysers is the world's largest geothermal field, containing a complex of 18 geothermal power plants, drawing steam from more than 350 wells, located in the Mayacamas Mountains approximately 72 miles (116 km) north of San Francisco, California.

The International Energy Agency is a Paris-based autonomous intergovernmental organisation which acts as a policy adviser to its member states, as well as major emerging economies to support energy security and advance the clean energy transition worldwide.

Abbreviated from the French Système international (d'unités) SI is the modern form of the metric system.

A CGS unit of equivalent dose, effective dose, and committed dose, which are measures of the health effect of low levels of ionizing radiation on the human body.

The Sun is the star at the center of the Solar System. It is by far the most important source of energy for life on Earth.

The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.
