What type of force is described as causing a material to be crushed?

Tension
Compression
Shear
Twisting

The correct answer is: Compression

The force described as causing a material to be crushed is compression. Compression occurs when a material is subjected to a pushing force that acts to reduce its volume, effectively squishing it together. This type of force is vital in various engineering and safety contexts, especially in structural design and analysis. When compression is applied to materials, they can experience deformation, resulting in changes in shape or volume. For example, concrete is strong under compressive forces, which is why it is commonly used in construction, while materials like rubber or foam may compress easily under the same conditions. Understanding this type of force is essential for ensuring that structures can withstand loads without failing due to crushing or buckling.
