so i can work out a question
which involves
solid brick pier having :...
...325mm square section, and 2.4m height, subjected to an axial load of 400kN

A compressive load is a type of external force that is applied to a material or structure, causing it to become compressed or squished. This force is directed towards the center of the object and acts to decrease the distance between its particles.
Compressive load is the opposite of tensile load, which is a force that pulls or stretches a material. Compressive load causes a material to contract and become shorter, while tensile load causes it to elongate and become longer.
Almost all materials can experience compressive load, including solids, liquids, and gases. However, some materials, such as fluids, are more likely to experience compressive load under specific conditions, such as when they are confined or subjected to high pressures.
Examples of compressive load in everyday life include sitting on a chair, stacking books on top of each other, or squishing a sponge. When you sit on a chair, your body weight exerts a compressive load on the chair's structure. When you stack books, the weight of the books creates a compressive load on the bottom book. And when you squish a sponge, you are applying compressive load to its particles, causing it to become smaller and more compact.
Compressive load can significantly affect the strength of a material, especially if the load is greater than the material's ability to withstand it. When a material is subjected to compressive load, its particles are pushed closer together, causing it to deform and potentially fail if the load is too great. However, some materials, such as concrete and steel, are better able to withstand compressive load than others.
