The compressive strength of plywood typically ranges from 1,000 to 2,000 pounds per square inch (psi), depending on the type, grade, and thickness of the plywood. Factors such as the wood species, adhesive used, and manufacturing process can also influence its strength. For specific applications, it's essential to consult the manufacturer's specifications or relevant standards.
Load divided by area of load applied (Load per unit area)
Concrete is cheaper. As in cheaper per kilogram, cheaper to "model". Has a relatively high compressive strength
The psi (pounds per square inch) of an 8 sack concrete mix typically refers to the compressive strength of the concrete. An "8 sack" mix generally contains 8 bags of cement per cubic yard of concrete, which can yield a compressive strength of approximately 4,500 to 5,000 psi, depending on the specific mix design and the quality of materials used. This strength makes it suitable for various structural applications, such as driveways and foundations.
M40 is a concrete mix design that typically has a compressive strength of 4,000 psi (pounds per square inch) at 28 days.
For M25 grade concrete the seven days crushing for site condition shall be not less than 67 % of M25, i.e not less than 16.75 N/mm2 But for target strength of M25 for mix design taken i.e for M25 it is 32 and the 7 days strength shall not be less than 22 N/mm2
The grade of concrete refers to its compressive strength measured in megapascals (MPa) or pounds per square inch (psi) after 28 days of curing. Common grades include M15, M20, M25, and so on, where the number indicates the characteristic strength of the concrete mix. Higher-grade concrete has a greater strength, making it suitable for structural applications requiring durability and load-bearing capacity. The selection of the appropriate grade depends on the specific requirements of the construction project.

As per the Indian standard specifications 3495 ,Compressive Strength, Water Absorption, Efflorescence and Dimensions are the tests to be carried out on bricks.
The ratio of compressive strength to the weight of a corrugated box can vary widely depending on the materials and design used. Typically, compressive strength is measured in pounds per square inch (psi), while the weight is measured in pounds. A higher ratio indicates a more efficient design, where the box can support more weight relative to its own weight, which is desirable for shipping and storage. This ratio is crucial in packaging engineering to optimize performance while minimizing material use.
