Force: |
(english) A directed interaction between two objects that tends to change the momentum of both.Since a force has both direction and magnitude, it can be expressed as a vector |
Funicular: |
(english) A funicular shape is one similar to that taken by a suspended chain or string subjected to a particular loading. |
Gravity: |
(english) An attractive force between two objects; each object accelerates at a rate equal to the attractive force divided by the object's mass. Objects near the surface of the earth tend to accelerate toward the earth's center at a rate of ; this value is often called the gravitational constant and denoted as g. |
Inelastic: |
(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. |
Inertia: |
(english) The tendency of an object at rest to remain at rest, and of an object in motion to remain in motion. |
Inertial Force: |
(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. |
Internal force: |
(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. |
Kinetic Energy: |
(english) The energy of a moving mass; equal to (mv^2)2. Where m is mass and v is the magnitude of the velocity. |
Linear: |
(english) A structure is said to behave linearly when its the deformation response is directly proportional to the loading (i.e. doubling the load doubles the displacement response). For a material, linear means that the stress is directly proportional to the strain. |
Line of Action: |
(english) The line of action of a force is the infinite line defined by extending along the direction of the force from the point where the force acts. |
