Mechanical Reasoning Test Practice
Drawings of machines and a question about what happens next. Everyday physics, not calculation, decides most of the items.
Mechanical Reasoning Practice Tests

Mechanical Reasoning
Work out how gears, pulleys, levers, fluids and simple circuits behave from short scenarios. Mirrors the SHL Verify Mechanical Comprehension test used for engineering and apprenticeship programmes. One clock for the whole test, no penalty for a wrong answer.

Mechanical Comprehension (MC)
The CAT-ASVAB mechanical subtest: 15 adaptive questions in 22 minutes, mostly from drawings of gears, pulleys, levers, ramps, springs and liquids, with some on structures and materials. It feeds the mechanical job scores of every service.

ACER Mechanical Reasoning (MRT-2)
Gears, belts, linked bars, levers and pulleys, simple machines, fluids and pressure, and forces and motion: 32 questions in 20 minutes on one clock. Mirrors the mechanical component of the Fire Rescue Victoria Written Selection Test and the off-the-shelf ACER MRT-2.

EEI Mechanical Concepts
The Mechanical Concepts subtest in CAST, CAST-R, MASS, POSS and TECH: 44 drawn mechanical situations in 20 minutes, each with three answers, the third often "equal". Gears, belts, pulleys, levers, ramps, fluids, springs and simple circuits.

DAA Mechanical Comprehension
Nineteen questions in 13 minutes on gears, belts, pulleys, levers, springs, pressure and forces, plus workshop tools and engineering drawing scales. Many are drawn. Mirrors the Mechanical Comprehension section of the Defence Aptitude Assessment.

Clevry Mechanical Reasoning (Essential)
Twenty drawn gears, pulleys, levers, hydraulics and forces in 12 minutes, 36 seconds each: the fastest pace in the Clevry suite and its only 20-question test.

Technisches Verständnis (Mechanical)
Drawn gears, belts, levers, pulleys, circuits, beams and vessels: which way it turns, how fast, what balances and what lights up. Adaptive over five levels, for applicants to technical assignments.
What Mechanical Reasoning Measures
Intuitive physics
Knowing how force, motion and pressure behave without working through formulas: which gear turns faster, which support carries more load, where a fluid will flow.
Reading technical drawings
Nearly every item is a diagram. Picking out the parts that matter, such as which gears mesh or where a pivot sits, is half of each question.
Practical knowledge
Some tests go beyond principles. The Defence Aptitude Assessment section includes workshop tools and engineering drawing scales, and the ASVAB adds questions on structures and materials.
Question Formats
Gears and belts
Which way does the last gear turn, and how fast? Meshed gears turn in opposite directions, and so do wheels joined by a crossed belt; an open belt keeps the direction.
Levers and beams
Where to place a weight to balance a beam, or which support carries more of a load. The closer a load sits to a support, the more of it that support takes.
Pulleys
How much effort lifts a load through a pulley system. In an ideal system, the load is shared between the rope sections holding up the moving pulley.
Fluids, pressure and heat
Which tank empties first, where water settles, which pipe flows faster. ACER MRT-2 covers fluids and pressure, and TMA Technisch Inzicht adds heat.
Three-option items
EEI Mechanical Concepts, TMA and TestGorilla often give a third answer such as equal or the same. When the drawing is symmetrical, it is a real answer, not a filler.
How to Prepare
Learn the handful of principles
Gear direction, mechanical advantage, moments, pressure with depth and simple series and parallel circuits cover most items. A page of notes on each beats a physics textbook.
Train at your test’s pace
Paces vary widely. Clevry Essential allows 36 seconds a question and TMA about 20, while EEI sets 44 items in 20 minutes and ACER MRT-2 32 in 20.
Reason before you calculate
Most items are designed to be answered by reasoning about direction or proportion. If you are reaching for a formula, look for a simpler comparison first.
Frequently Asked Questions
What is a mechanical reasoning test?
A test of how well you understand basic mechanical and physical principles, using drawings of gears, pulleys, levers, springs, fluids and simple circuits. It is set for engineering apprenticeships, the armed forces, fire services and plant operator roles.
Is a mechanical comprehension test the same thing?
Yes. Mechanical comprehension, mechanical reasoning, mechanical aptitude and technical insight are vendor names for the same item type. The ASVAB and the DAA call it Mechanical Comprehension, EEI calls it Mechanical Concepts and TMA calls it Technisch Inzicht.
Do I need an engineering background?
No. The tests assume everyday physics, not qualifications, and the principles behind most items can be learned in a few evenings of practice.
Does ASVAB Mechanical Comprehension count towards the AFQT?
No. The AFQT, which decides whether you can enlist, is built from Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension. Mechanical Comprehension feeds the line scores the services use to decide which jobs you qualify for.
