Simple Machines, Force, Torque, Work, Energy, and Motion
Mechanical-comprehension questions test levers, pulleys, gears, wheels, inclined planes, force, torque, work, energy, friction, acceleration, and mechanical advantage.
How to study for the ASVAB
Use the official ASVAB subtests as your map: build AFQT math and verbal accuracy first, then add science, technical, mechanical, auto, shop, and spatial practice.
Core concepts
Concept 1
Simple Machines, Force, Torque, Work, Energy, and Motion questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Lever
A lever rotates around a fulcrum and can trade force for distance.
Pulley
A pulley changes force direction or provides mechanical advantage when arranged in systems.
Gear
Gears transfer rotation and can change speed, torque, or direction.
Inclined Plane
An inclined plane reduces force needed by spreading work over a longer distance.
Torque
Torque is rotational force and depends on force size and distance from the pivot.
Work
Work occurs when force moves an object through distance in the force direction.
Friction
Friction opposes motion between surfaces in contact.
Mechanical Advantage
Mechanical advantage compares output force to input force in a machine.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
