Jan 12, 2011 · In the experiment, testing the compressive strength of wood, which is the measurement of the largest compression force the material can withstand before it loses its shape or fails, the students used two samples (wood parallel and perpendicular to the grain). Compression parallel to the grain shortens the fibers in the wood lengthwise.

Compressive strength is the capacity of a material to withstand axially directed pushing forces. When the limit of compressive strength is reached, materials are crushed. Concrete can be made to have high compressive strength, e.g. many concrete structures have compressive strengths in excess of 50 MPa, whereas a material such as soft sandstone may have a compressive strength as low as 5 or .
