Which ASVAB subtest focuses on knowledge related to mechanical principles?

The ASVAB subtest that focuses on knowledge related to mechanical principles is Mechanical Comprehension. This subtest assesses a candidate's understanding of basic mechanical concepts, such as the effects of forces, the principles of levers, pulleys, and gears, as well as the functioning of various machines and how they interact.

Mechanical Comprehension questions often involve visual interpretations of mechanical systems or scenarios, where the individual must apply their knowledge of physics and mechanics to understand how different parts work together. This skill is crucial for many military roles that require technical expertise in operating and maintaining machinery and equipment.

While there are other subtests like Math Knowledge and Word Knowledge that assess numerical reasoning and vocabulary, respectively, they do not specifically target mechanical principles. Auto and Shop Information relates more to automotive systems and shop practices but is not as focused specifically on mechanical concepts as Mechanical Comprehension.
