Strain energy definitions? Strain energy is a form of potential energy. Work done to distort an elastic member is stored as strain energy.Some energy may be lost in plastic deformation of the member and some may be converted into heat instead of stored as strain energy, but the rest is recoverable.A spring is an example of a storage device for strain energy.train energy is a form of potential energy. Work done to distort an elastic member is stored as strain energy.

Heat Transfer Heat Transfer. Heat transfer, also referred to simply as heat, is the movement of thermal energy from one thing to another thing of different temperature. These objects could be two solids, a solid and a liquid or gas, or even within a liquid or gas.

heat The definition of heat is a form of energy that causes a difference in temperature, or the perception of warmth. An example of heat is hot water. Heat is defined as to add warmth to something. An example of heat is bringing a kettle of water to a boil. the quality of being hot; hotness: in physics, heat is considered a form of energy existing as the result of the random motion of molecules and is the form of energy that is transferred between bodies as a result of their temperature difference.

- ‘The three types of heat-induced illnesses include heat strain, heat exhaustion, and heatstroke.’ ‘Wet clothing is used to reduce the temperature in heatstroke.’ ‘It is important to remember that heat exhaustion, if not promptly treated, can lead to heatstroke, and that the two conditions may overlap, making vigilance of the utmost importance.’

Hyperthermia (Redirected from Heat stress). Hyperthermia is elevated body temperature due to failed thermoregulation that occurs when a body produces or absorbs more heat than it dissipates. Extreme temperature elevation then becomes a medical emergency requiring immediate treatment to prevent disability or death.

Lower Back Pain Medical Definition of Lumbar strain Lumbar strain: A stretching injury to the ligaments, tendons, and/or muscles of the low back. The stretching incident results in microscopic tears of varying degrees in these tissues. Lumbar strain is one of the most common causes of low back pain. The injury can occur because of overuse, improper use, or trauma. It is classified as acute if it has been present for days to weeks.

Heat-Affected Zone (HAZ) Definition - What does Heat-Affected Zone (HAZ) mean? A heat-affected zone (HAZ) is the portion of the base metal that was not melted during brazing and cutting/welding, but whose microstructure and mechanical properties were altered by the heat. This alteration can be detrimental, causing stresses that reduce the strength of the base material, leading to catastrophic failures.

Heat Radiation Heat Radiation. a form of electromagnetic radiation emitted by a substance as a result of its internal energy. Heat radiation is contrasted, for example, to luminescence, which results from external energy sources. Heat radiation has a continuous spectrum whose maximum is a function of the temperature of the substance.

Thermal Injuries Heat Prostration(heat exhaustion; heat syncope, or heat collapse): Heat prostration is a condition of collapse without increase in body temperature, which follows exposure to excessive heat. It is precipitated by muscular work and unsuitable clothing. There is extreme exhaustion and peripheral vascular collapse.

Muscle Strain What Is a Muscle Strain? Muscle strain is injury to muscle as a result of strenuous activity. Almost anyone can put undue tension on muscles during the course of normal daily activities, with sudden, quick heavy lifting, during sports, or while performing work tasks. Muscle strain is sometimes referred to as muscle pull.

- Strain = A change in shape or volume in response to a stress. Stress is the cause, strain is the effect! There are three types of stress: 1) Compressive stress  Forces that squeeze or push toward one another from opposite directions (cause shortening or flattening). 2) Tensional stress  Forces that pull away from one another in opposite directions (cause stretching or extension).

Medical Definition of Heat-related illness Definition of Heat syncope. Heat syncope: Sudden dizziness, feeling faint and sometimes fainting experienced after exercising in the heat. The skin appears pale and sweaty but is generally moist and cool. The pulse may be weakened, and the heart rate is usually rapid. Body temperature is normal.

Muscle Strain Muscle Strain Overview. Muscle strain is injury to muscle as a result of strenuous activity. Almost anyone can put undue tension on muscles during the course of normal daily activities, with sudden, quick heavy lifting, during sports, or while performing work tasks.Muscle strain is sometimes referred to as muscle pull. severe muscle strain can result in a muscle tear. The tearing of the muscle can also damage small blood vessels, causing local bleeding (with or without bruising) and pain (caused by irritation of the nerve endings in the area).

Thermal diffusivity In heat transfer analysis, thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure. It measures the rate of transfer of heat of a material from the hot side to the cold side. It has the SI derived unit of m²/s. Thermal diffusivity is usually denoted α but a, κ, K, and D are

Strain Strain is the measure of deformation in a material or object. Normal strain, ε (epsilon), expresses the change in the location of a point. A positive normal strain indicates that the material has been lengthened, whereas a negative normal stress indicates the material has contracted.

Overview Definition. Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury, heatstroke can occur if your body temperature rises to 104 F (40 C) or higher. Heatstroke requires emergency treatment. Untreated heatstroke can quickly damage your brain, heart, kidneys and muscles. The damage worsens the longer treatment is delayed, increasing your risk of serious complications or death.
