The tool used to measure the compression in various materials is the compression tester. This device is specifically designed to apply a compressive load to a material sample and measure the resulting deformation. By quantifying how much a material compresses under pressure, the compression tester provides critical data on material properties such as strength, ductility, and failure point, which are essential in material selection and quality control processes in agricultural mechanics and related fields. The pressure gauge primarily measures the pressure of gases or liquids rather than the mechanical compression of solid materials. A force meter measures the force applied to an object but does not necessarily provide direct information on compression properties. The torque wrench is used to apply a specific amount of torque to fasteners, which is important in assembly but does not relate directly to measuring compression in materials. Each of these tools serves a different purpose, making the compression tester the suitable option for assessing material compression.
