The transition from one energy conversion system to another is impossible without the real physical parameters of the inertia of any object (for example, meters and centimeters to the fourth degree).
When calculating building structures, inertia in m4 and cm4 is a practical calculation method.
Dimensional drawing is a document containing a contour (simplified) image of a product with overall, installation and connecting dimensions.
The work of the m4 and cm4 program determines the meaning of the power of knowledge.
