Partial overlap box with interlocking slots to temporarily close box Corrugated plastic box used as reusable packaging. Corrugated box design is the process of matching design factors for corrugated fiberboard (sometimes called corrugated cardboard) or corrugated plastic boxes with the functional physical, processing and end-use requirements.
Containers can be subjected to compression forces that involve distribution dynamics. For example, a package may be impacted by an object being dropped onto it (vertical load) or impacted by freight sliding into it (horizontal load). Vehicle vibration can involve a stack of containers and create dynamic compression responses. [13]
Packing circles in a square - closely related to spreading points in a unit square with the objective of finding the greatest minimal separation, d n, between points. To convert between these two formulations of the problem, the square side for unit circles will be L = 2 + 2 / d n {\displaystyle L=2+2/d_{n}} .
A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction ...
Reach truck handling stretch wrapped unit load Air cargo container of the AKH type on a trailer. The term unit load refers to the size of an assemblage into which a number of individual items are combined for ease of storage and handling, [1] for example a pallet load represents a unit load which can be moved easily with a pallet jack or forklift truck, or a container load represents a unit ...
Dimensional weight, also known as volumetric weight, is a pricing technique for commercial freight transport (including courier and postal services), which uses an estimated weight that is calculated from the length, width and height of a package. The shipping fee is based upon the dimensional weight or the actual weight, whichever is greater.
The dead load includes loads that are relatively constant over time, including the weight of the structure itself, and immovable fixtures such as walls, plasterboard or carpet. The roof is also a dead load. Dead loads are also known as permanent or static loads. Building materials are not dead loads until constructed in permanent position.
