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.

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.

Body force:

แปลว่า(english) An external force acting throughout the mass of a body. Gravity is a body force. An inertial force is a body force.

Static equilibrium:

แปลว่า(english) Equilibrium which does not include inertial forces.

Dynamic equilibrium:

แปลว่า(english) Equilibrium which includes inertial forces.

Section Modulus:

แปลว่า(english) A property of a cross sectional shape, which depends on shape, and orientation. Section modulus is usually denoted S, and S = I/c, where I = moment of inertia about an axis through the centroid, and c is the distance from the centroid to the extreme edge of the section.
