Free Bennett Mechanical Comprehension Test Practice: BMCT-II Simulation
The Bennett Mechanical Comprehension Test is the oldest mechanical aptitude test still in hiring use, first published in 1940 and now in its second major revision (BMCT-II). This free simulation covers the 68-item, 30-minute format used by Boeing, GE, Siemens, Lockheed Martin, Ford, and most US heavy manufacturing hiring.
What this free Bennett Mechanical practice includes
The BMCT-II measures understanding of physical principles most people learn by doing rather than by studying. Leverage, gears, pulleys, fluid dynamics, center of gravity, structural integrity, and spatial visualization. It is a literacy test for anyone working with physical systems: engineers, skilled tradespeople, military mechanical specialists, and manufacturing supervisors.
This free practice presents 68 items with the exact difficulty distribution of the real BMCT-II. Half of the items use straightforward mechanical principles that most engineering graduates can answer in 10 seconds. The other half require reasoning through systems with three or more interacting components. At the end, you get a raw score, a percentile against a general-population norm, and full diagrams in the answer walkthroughs.
Three sample Bennett Mechanical questions with walkthroughs
BMCT-II items are always diagram-based in the real test. Text descriptions here still walk the same physical reasoning.
- A.6 kg
- B.8 kg
- C.9 kg
- D.12 kg
- E.18 kg
- A.Clockwise at 30 RPM
- B.Clockwise at 72 RPM
- C.Counterclockwise at 36 RPM
- D.Clockwise at 48 RPM
- E.Counterclockwise at 72 RPM
- A.Pipe 1 discharges more.
- B.Pipe 2 discharges more.
- C.Both discharge equally.
- D.Depends on the water temperature.
- E.Cannot be determined without more information.
What the real BMCT-II feels like
The real Bennett Mechanical Comprehension Test II is delivered through Pearson TalentLens or through an employer-branded portal. Every item is diagram-based: you see a physical scenario illustrated, and you pick the answer that describes the correct physical outcome. The interface is clean: one diagram, 3 to 5 answer choices, a clock, and a next button.
Boeing uses the BMCT-II as a screening gate for engineering and technician roles at both commercial and defense divisions. GE uses it for manufacturing supervisor hiring. Siemens uses it for technical sales and field engineer hiring. Lockheed Martin uses it for mechanical specialist roles, particularly at the Skunk Works and classified program divisions where the security clearance process filters on measurable technical literacy.
The typical hiring cutoff is the 60th to 70th percentile against a general population norm. For engineering roles at Boeing and Lockheed, the cutoff is closer to 80th percentile. Unlike cognitive speed tests, the BMCT-II is not primarily a timing test. Candidates who have a strong physical-intuition base typically finish with time to spare. The weakness for most candidates is not speed, it is recognizing which mechanical principle applies to a given diagram.
