Physical Methods
The second technique treats cloth like a grid work of particles connected to each other by springs. Whereas the geometric approach accounted for none of the inherent stretch of a woven material, this physical model accounts for stretch (tension), stiffness, and weight:
- s terms are elasticity (by Hooke's Law)
- b terms are bending
- g terms are gravity (see Acceleration due to gravity)
Now we apply the basic principle of mechanical equilibrium in which all bodies seek lowest energy by differentiating this equation to find the minimum energy.

Famous quotes containing the words physical and/or methods:
“Our own physical body possesses a wisdom which we who inhabit the body lack. We give it orders which make no sense.”
—Henry Miller (1891–1980)
“Parents ought, through their own behavior and the values by which they live, to provide direction for their children. But they need to rid themselves of the idea that there are surefire methods which, when well applied, will produce certain predictable results. Whatever we do with and for our children ought to flow from our understanding of and our feelings for the particular situation and the relation we wish to exist between us and our child.”
—Bruno Bettelheim (20th century)
