System of Forces:

แปลว่า(english) One or more forces and/or moments acting simultaneously.

internal forces

แปลว่าแรงภายใน

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Bending moment:

แปลว่า(english) A system of internal forces whose resultant is a moment. This term is most commonly used to refer to internal forces in beams.

Concentrated force:

แปลว่า(english) A force considered to act along a single line in space. Concentrated forces are useful mathematical idealizations, but cannot be found in the real world, where all forces are either body forces acting over a volume or surface forces acting over an area.

Inertial Force:

แปลว่า(english) A fictitious force used for convenience in visualizing the effects of forces on bodies in motion. For an accelerating body, the inertial force is considered as a body force whose resultant acts at the object's center of gravity in a direction opposite the acceleration. The magnitude of the force is the mass of the object times the magnitude of the acceleration.

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.

Statically determinate:

แปลว่า(english) A statically determinate structure is one where there is only one distribution of internal forces and reactions which satisfies equilibrium. In a statically determinate structure, internal forces and reactions can be determined by considering nothing more than equations of equilibrium.

Pin support:

แปลว่า(english) In two dimensions, a pin support restrains two translation degrees of freedom but does not restrain rotation. When considering reaction forces, a pin support is usually considered to have two force components: one each about the x and y axes respectively.

Stress resultant:

แปลว่า(english) A system of forces which is statically equivalent to a stress distribution over an area.

External force:

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

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.
