Internal force:

แปลว่า(english) Forces which hold an object together when external forces or other loads are applied. Internal forces are sometimes called resisting forces since they resist the effects of external forces.

Deflection:

แปลว่า(english) This word usually carries the same meaning as displacement, although it is sometimes used in place of deformation.

Hydrogenesis

แปลว่า(Concrete Engineering) Another term for condensation. The term is especially applied to base and soil substrates under highway pavements. where the barometric pump causes the inhalation of humid air, which then condenses in those structures, causing an ever increasing moisture content and sometimes instability.

Load:

แปลว่า(english) An external force. The term load is sometimes used to describe more general actions such as temperature differentials or movements such as foundation settlements.

Reaction:

แปลว่า(english) A reaction is a force exerted by a support on an object: sometimes called support reaction. Using this definition, a reaction is an external force.

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.

Kelly Ball

แปลว่า(Concrete Engineering) A device for determining the consistency of fresh concrete. It is sometimes used as an alternative to the slump test.

Yield stress:

แปลว่า(english) A material loaded beyond its yield stress, no longer exhibits linear elastic behavior. Metals, particularly mild steel, generally have a very well defined yield stress compared to other materials. Yield stress is sometimes called yield strength.

Bloom 2

แปลว่า(english) A semi-finished hot rolled product, rectangular in cross section, produced on a blooming mill. For iron and steel, the width is not more than twice the thickness, and the cross-sectional area is usually not less than 36 sq. in. Iron and steel blooms are sometimes made by forging.

Box Annealing

แปลว่า(english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing.

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.

External force:

แปลว่า(english) A surface force or body force acting on an object. External forces are sometimes called applied forces.
