Inertia:

แปลว่า(english) The tendency of an object at rest to remain at rest, and of an object in motion to remain in motion.

Moment of inertia (I):

แปลว่า(english) Moment of inertia has two distinct but related meanings: 1) it is a property of a an object relating to the magnitude of the moment required to rotate the object and overcome its inertia. 2) A property of a two dimensional cross section shape with respect to an axis, usually an axis through the centroid of the shape.

Statically equivalent:

แปลว่า(english) Two force systems are statically equivalent when their resultants are equal. Physically, this means that the force systems tend to impart the same motion when applied to an object; note that the distribution of resulting internal forces in the object may be different.

Statically indeterminate:

แปลว่า(english) A statically indeterminate structure is one where there is more than one distribution of internal forces and/or reactions which satisfies equilibrium.

Scalar:

แปลว่า(english) A mathematical entity which has a numeric value but no direction (in contrast to a vector).

Pressure:

แปลว่า(english) Pressure is a similar idea to stress, the force intensity at a point, except that pressure means something acting on the surface of an object rather than within the material of the object. When discussing the pressure within a fluid, the meaning is equivalent to stress.

Inelastic:

แปลว่า(english) Not surprisingly, the opposite of elastic. A deformation of a structure or material under load is described as inelastic when the deformation remains after the load is removed. The term plastic is often used with the same meaning.

Racking:

แปลว่า(english) The distortion of a rectangular shape to a skewed parallelogram.

Energy:

แปลว่า(english) A property of a body related to its ability to move a force through a distance opposite the force's direction; energy is the product of the magnitude of the force times the distance. Energy may take several forms: see kinetic energy, potential energy, and elastic energy.

Strain:

แปลว่า(english) The intensity of deformation at a point in an object. See normal strain and shear strain.

Fixed support:

แปลว่า(english) In two dimensions, a fixed support restrains three degrees of freedom: two translations and one rotation.

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.
