In mechanics, a moment is a measure of the turning effect of a force about some point in space. In most practical examples, moments are the results of forces acting at a distance from the point of interest. The stress on the body on which the force acts is then symmetric. If the moment results from a strong body force, such as that produced in a magnetic material in a strong magnetic field, the stress tensor is non-symmetric.
Famous quotes containing the words body and/or moment:
“It is so much more difficult to live with one’s body than with one’s soul. One’s body is so much more exacting: what it won’t have it won’t have, and nothing can make bitter into sweet.”
—D.H. (David Herbert)
“To a man of pleasure every moment appears to be lost, which partakes not of the vivacity of amusement.”
—Joseph Addison (1672–1719)
