Anatomy & Physiology Chapter 1.3 Terms

Shear

-A force that acts along a surface & perpendicular to the length of a structure.

Bending

-A loading pattern created by a combination of off-center forces.

Torsion

-A loading pattern that can cause a structure to twist about its length.

Tension

-A pulling force that creates tension in the structure to which it is applied.

Elastic

-A response that occurs when force is removed & the structure returns to its original size & shape.

Compression

-A squeezing force that creates compression in the structure to which is applied.

Pressure

-Force distributed over a given area.

Stress

-Force distribution inside a structure.

Weight

-Force equal to the gravitational acceleration exerted on the mass of an object.

Force

-Push or pull acting on a structure.

Kinetics

-The analysis of the actions of forces.

Mass

-The quantity of the actions of forces.

Torque

-The rotary effect of a force.

Combined Loading

-The simultaneous action of two or more types of forces.

Net Force

-The single force resulting from the summation of all forces acting on a structure at a given time.
