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