What is the Bennett Mechanical Comprehension Test (BMCT-II)
The Bennett Mechanical Comprehension Test, Second Edition (BMCT-II) is a standardized mechanical reasoning test published by Pearson TalentLens. It's one of the most widely used mechanical aptitude tests in the world, used by employers in manufacturing, utilities, refineries, technician hiring, and trades apprenticeships. The test has 55 multiple-choice questions in 25 minutes — meaning speed matters as much as accuracy. Every question uses a diagram: gears, pulleys, levers, springs, gravity, fluids, and simple machines.

4 real-format questions covering the sections you'll see on test day. Pick an answer for instant feedback, and read the worked explanation under each one — no signup needed.
- Question 1 of 4Mechanical ReasoningTwo wheels of different sizes are on the same axle. The large wheel has a radius of 12 inches, the small wheel 4 inches. If the large wheel makes one full rotation, how far does a point on the rim of the small wheel travel?
Step-by-step explanation
Wheels on the same axle share angular velocity (same RPM). Distance = 2πr. One rotation of the small wheel = 2π × 4 = 8π inches. The wheel-and-axle is one of the six simple machines the BMCT-II tests heavily.
- Question 2 of 4Mechanical ReasoningA 100 lb weight sits on the left end of a lever, 3 ft from the pivot. How much force is needed 6 ft from the pivot on the right side to balance it?
Step-by-step explanation
Lever balance: weight × distance on each side must be equal. Left side: 100 × 3 = 300. Right side: F × 6 = 300, so F = 50 lb. Longer lever arm → less force needed. Draw the pivot before you compute.
- Question 3 of 4Mechanical ReasoningWater flows through a pipe that narrows from 4 inches diameter to 2 inches diameter. What happens to the water's speed in the narrow section?
Step-by-step explanation
Continuity: flow rate = area × velocity, and area depends on radius squared. Halving the diameter cuts area to 1/4, so velocity must quadruple to keep flow constant. Fluid-flow items appear on every BMCT-II.
- Question 4 of 4Mechanical ReasoningA block-and-tackle system supports a load with 4 rope segments. Ignoring friction, how much force is needed on the free end to lift a 400 lb load?
Step-by-step explanation
Mechanical advantage of a block-and-tackle equals the number of rope segments supporting the load. 400 ÷ 4 = 100 lb of force required. Trade-off: you pull 4× the distance. Count rope segments, not pulleys.

Test format
One timed section, no calculator. 55 questions in 25 minutes — roughly 27 seconds per question. Proctored online administration is offered by Pearson TalentLens.
| Section | Questions | Time | Focus |
|---|---|---|---|
| Mechanical Comprehension | 55 | 25 minutes | Gears, pulleys, levers, springs, hydraulics, gravity, tools, basic electricity — all diagram-based. |
Scoring explained
The BMCT-II is scored as a raw number correct (out of 55), converted to a percentile score against one of Pearson's norm groups — for example, industrial workers or applicants for a specific job family.
What counts as a strong result depends on the norm group and the employer's cutoff — most employers screen on percentile rather than raw score.
You typically get a percentile score and a short interpretation. Retest policy is set by the employer; a waiting period of several months or one hiring cycle is common.
How to prepare
The BMCT-II punishes slow readers. 25 minutes for 55 diagram-based questions is roughly 27 seconds each — you can't reason from scratch on every one. Preparation is about pattern recognition speed.
- Learn the diagram vocabulary — every pulley type, gear train, lever class, fluid system. One session each.
- Drill at pace — 55 questions in 25 minutes, three times a week. Track your time per question.
- Review the wrong ones — after every timed set, work through why each miss was wrong. That's where the improvement happens.
- Warm up before test day — 10 quick questions the morning of. Cold starts cost points.
