Final answer:
Metals can indeed be modified to increase their resistance to shearing, forces of torque, and deformation, which is true.
Step-by-step explanation:
True or false: metals are modified to increase resistance to shearing, forces of torque, and deformity. The answer is true. Metals can be modified through processes such as alloying to enhance their mechanical properties, including resistance to shearing and deformation under forces of torque. For example, steel is produced from iron by removing impurities and adding other elements to form an alloy with specific, desirable characteristics. Just as ball bearings coated in oil slide past each other, the free-flowing electrons in metals allow for slippage between cations, granting metals their noted malleability and ductility.
