ASVAB MechanicalComprehension

ASVAB Mechanical Comprehension is a subtest of the ASVAB exam that is used in many composite or line scores to establish the suitability of a candidate to engineering style or related roles in the military.

Here in this ASVAB mechanical comprehension guide, we learn more about the exam format; syllabus of questions; as well as the top tips you need to apply to score the highest possible result.

ASVAB Mechanical Comprehension Exam Format

Depending on whether you are taking the CAT-ASVAB or the P&P ASVAB, there are different numbers of questions asked and time allotted.

To score high on the ASVAB mechanical comprehension exam, candidates must have a rounded knowledge of three main themes.

These themes include mechanical systems; motion and forces; and fluid dynamics.

  • Mechanical Systems

    Candidates are often shown a mechanical system, such as a pulley and gear, and asked – if a force were applied to one part of this system, how would it impact the rest of the system. Illustrative questions may also be asked about wheels and axles; vises; inclined planes; fulcrums and levers; and mechanical advantage.

  • Fluid Dynamics

    Fluid dynamics concerns the principles that underscore how liquids flow and impact systems when pressure is applied. A small number of questions may be asked about fluid dynamics. If you want to score high on the mechanical comprehension exam, you will need to invest some time understanding the principles of hydraulics and hydraulic jacks, in particular.

  • Motion and Forces

    You will also be asked questions about fundamental physics – and how these physical principles impact mechanical systems and machines. These concepts include subjects such as the kinds of forces in the universe; laws of gravity and motion; equilibrium; pressure, force, and area; friction and resistance; centrifugal force; and elasticity. You may also be asked math questions that talk about the equations that describe these principles.

Test Taking Tips!

To score high at the ASVAB mechanical comprehension exam, candidates must study in the
weeks and months leading up to the exam – taking as many ASVAB test questions as

  • 1Get hands-on experience. Become familiar with machines and mechanical processes through hands-on experience. You may know a friend or family member who can assist you with this goal. You can also go to a local store and go through the various mechanical systems with members of staff. Alternatively, you can use the next-best thing – which is YouTube videos, free of charge, that go through this process for you.
  • 2Get to grips with equations. Though math and equations do not form a huge part of the mechanical comprehension test, they do get asked. And once you understand the equations, the questions are quite easy to solve. These equations include things such as Force = Mass x Acceleration; and Work = Force x Distance. Do not forget to know the correct units for each factor of these equations, too!
  • 3Practice ASVAB test questions. Mechanical comprehension is one of those exams that is very image-oriented. You will be presented with many images and asked to interpret what would happen if a force were applied, for example. That’s why ASVAB test practice questions are so important. They give you the chance to work out exam-like questions from home and ace these same questions on the day of your exam.
  • 4Create ASVAB flashcards. Flashcards are one of the time-honored ways of learning vast numbers of facts in a short timeframe. Always create original facts for each card – written in your own words. This makes the cards far more memorable.
