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.

External force:

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

Balanced Steel

แปลว่า(english) Steels in which the deoxidisation is controlled to produce an intermediate structure between a rimmed and killed steel, Sometimes referred to as semi-killed steels, they possess uniform properties throughout the ingot and amongst their applications are boiler plate and structural sections.

Body-Centered

แปลว่า(english) Having the equivalent lattice points at the corners of the unit cell, and at its center; sometimes called centered, or space-centered.

Shear:

แปลว่า(english) An system of internal forces whose resultant is a force acting perpendicular to the longitudinal axis of a structural member or assembly: sometimes called shear force.

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.

Modulus of elasticity:

แปลว่า(english) The proportional constant between stress and strain for material with linear elastic behavior: calculated as stress divided by strain. Modulus of elasticity can be interpreted as the slope of the stress-strain graph. It is usually denoted as E, sometimes known as Young's Modulus Y, or E-Modulus.

Deflection:

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

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.

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.

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.

Center of Gravity (CG):

แปลว่า(english) The location of the resultant of gravity forces on an object or objects: sometimes called center of mass.
