As is well known the principle of virtual velocities…
“As is well known the principle of virtual velocities transforms all statics into a mathematical assignment, and by D'Alembert's principle for dynamics, the latter is again reduced to statics. Although it is is very much in order that in gradual training of science and in the instruction of the individual the easier precedes the more difficult, the simple precedes the more complicated, the special precedes the general, yet the min, once it has arrived at the higher standpoint, demands the reverse process whereby all statics appears only as a very special case of mechanics.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The principle shows that dynamics can be reduced to statics, and statics to a special case of mechanics, illustrating a hierarchical learning order.
In simple terms: Dynamics can be simplified to static analysis, then to special cases.
