2. Container compression test - Wikipedia

   en.wikipedia.org/wiki/Container_compression_test

   The dynamic loads have some relationship with expected field loads.: [3] often factors of 4 or 5 are used to estimate the allowable working load on boxes. A test can also be conducted with platens that are not mechanically driven but are free to move with a fixed mass (or fixed force) loaded upon them. [4] The results of static load testing can be:

3. Packing problems - Wikipedia

   en.wikipedia.org/wiki/Packing_problems

   Packing identical rectangles in a rectangle: The problem of packing multiple instances of a single rectangle of size (l,w), allowing for 90° rotation, in a bigger rectangle of size (L,W) has some applications such as loading of boxes on pallets and, specifically, woodpulp stowage. For example, it is possible to pack 147 rectangles of size (137 ...

   Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
