#structural physics
- Amphidromic — The feminine singular form of the adjective 'amfidromic'; describes a region, zone, or dynamic structure within a marine or ocean basin characterized by a nodal point where the tidal amplitude is zero, and cotidal lines converge and rotate circularly under the influence of the Coriolis force.
- Annuloid — Resembling a ring or a torus in shape, without strictly fulfilling their perfect geometric criteria; (noun) a three-dimensional surface or body generated by rotating a closed curve around an axis located in the same plane, used in designing circular mechanical components.
- To burn — To be destroyed or consumed by fire, to be in a state of combustion, emitting heat and light; to subject an object to the action of high temperatures (baking, calcination, sterilization). In a medical or physiological sense, it means to produce a stinging sensation, high fever, or acute pain similar to a thermal burn, while figuratively it expresses an intense desire, consuming passion, or extreme haste.
- Areopycnometer — A hybrid laboratory instrument used for the high-precision measurement of liquid density or the specific gravity of chemical solutions. This device structurally combines the hydrostatic operational principle of the hydrometer (based on the volume of displaced liquid) with the rigid volumetric technique of the pycnometer, ensuring superior calibration and accuracy by partially eliminating errors caused by ambient temperature variations.
- Solar exposure — The act of sunning or becoming exposed to sunlight and its result; the structural process of solar exposure or the onset of sunny weather following a cloudy period; the interval of time during which an object, land, or organism benefits from direct insolation.
- Autorotation — An aerodynamic mechanism and emergency flight regime of a helicopter or rotary-wing aircraft, where the main rotor spins exclusively under the action of the ascending airflow, without engine power. This physical phenomenon allows the aircraft to descend in a controlled manner and land safely in the event of a major failure or complete failure of the propulsion system.
