Elastic energy:

แปลว่า(english) The energy stored in deformed elastic material (e.g., a watch spring). Elastic energy equals where k is the stiffness, and is the associated deflection. Elastic energy is sometimes called elastic potential energy because it can be recovered when the object returns to its original shape; see potential energy.

Bronze

แปลว่า(english) An alloy containing 90% copper and 10% tin. Used for screws, wire, hardware, wear plates, bushings and springs; it is somewhat stronger than copper and brass and has equal or better ductility.

Acceleration:

แปลว่า(english) A vector quantity equal to the rate that velocity changes with time.

equalizer wire

แปลว่า(ไฟฟ้า) สายไฟต่อระหว่างสองเครื่องกำเนิดไฟฟ้าซึ่งต่อสายไฟขนาน โดยปล่อยกระแสไฟผ่านเท่า ๆ กัน

Mass balance

แปลว่า(Environmental Engineering) An organized accounting of all inputs and outputs to an arbitrary but defined system. Stated in other terms, the rate of mass accumulation within a system is equal to the rate of mass input less the rate of mass output plus the rate of mass generation within the system.

Velocity:

แปลว่า(english) A vector quantity equal to the rate that position changes with time.

Couple:

แปลว่า(english) A system of forces composed of two equal forces of opposite direction, offset by a distance. A couple is statically equivalent to a moment whose magnitude equals the magnitude of the force times the offset distance.

equal angle

แปลว่าเหล็กฉากขาเท่ากัน

Potential Energy:

แปลว่า(english) The energy stored in a raised object (e.g. the weights in a grandfather clock). Potential energy equals mgh, where m is mass, g is the acceleration of gravity, and h is the vertical distance from a reference location. It is called potential energy because the energy can be regained when the object is lowered. This type of potential energy is sometimes called gravitational potential energy in order to distinguish it from elastic potential energy: see elastic energy.

Covalent bond

แปลว่า(Environmental Engineering) A bond in which electrons are shared approximately equally by two atoms.

Kinetic Energy:

แปลว่า(english) The energy of a moving mass; equal to (mv^2)2. Where m is mass and v is the magnitude of the velocity.

Gravity:

แปลว่า(english) An attractive force between two objects; each object accelerates at a rate equal to the attractive force divided by the object's mass. Objects near the surface of the earth tend to accelerate toward the earth's center at a rate of ; this value is often called the gravitational constant and denoted as g.
