Aon lists mtu as a 15-minute test of mechanical and technical understanding. We cover what is official and give original practice items.
Aon lists Mechanical Reasoning (mtu) as 15 minutes to complete 24 tasks, measuring mechanical and technical understanding using mechanical graphics, with you selecting the correct answer. Aon publishes no dedicated mtu practice PDF on its candidate page, and the exact topic list is not publicly confirmed.
Aon's candidate page gives three facts about this test: the time (15 minutes), the number of tasks (24), and the description (mechanical and technical understanding using mechanical graphics, selecting the correct answer). Everything below that level of detail, including which mechanisms appear and how many options each question has, is not publicly confirmed.
In the wider field of mechanical aptitude testing, questions often draw on everyday physics: levers, gears, pulleys, simple circuits and fluid pressure. We use these as practice themes because they are standard in this kind of test. That does not mean every one appears in Aon's version, and the worked examples are our own.
Because the test uses graphics, the drawing carries the information. Learn to read pictures of arms, wheels and ropes rather than to recall formulas alone.
These are text versions of pictures you would normally see. Each answer was checked with a short calculation.
Remember to check what the question asks: force, speed, distance or direction. The same picture can ask about any of them.
If you attempted every task, the average is about 37 seconds each. Whether Aon expects candidates to finish every task is not stated for this test, so do not assume that either way.
Treat the list as general background rather than a confirmed syllabus for this Aon test.
ReasonEra's strongest overlap with this test is in spatial and diagrammatic question types, where you interpret a picture to answer a question. If you find a practice mechanical question online, take a screenshot, attempt it yourself and use Tutor Explanation to see the force path written out step by step. We cannot say how closely any third-party item matches Aon's, so use practice questions to train method rather than to predict content.
Your free account includes 3 free trials, and a 14-Day Pass costs 49 € for unlimited use for 14 days. The free spatial and diagrammatic practice test below is a good warm-up for picture-based reasoning.
Publishers update their tests and employers swap providers, so check your own invitation for the final word.
We built ReasonEra to help you understand how reasoning questions work, but a real assessment usually comes with its own conditions on outside help, so ask the recruiter if anything is unclear.
It is Aon's Mechanical Reasoning test. Aon lists 15 minutes for 24 tasks measuring mechanical and technical understanding using mechanical graphics.
Aon does not publish a topic list, so the exact topics are not publicly confirmed. Levers, gears and pulleys are common in mechanical aptitude tests in general, but treat them as practice themes.
Aon lists 24 tasks in 15 minutes. That averages roughly 37 seconds per task if all are attempted.
Aon says no special prior knowledge is required for its tests in general. Everyday mechanical understanding and careful reading of the graphic are what help.
No dedicated mtu practice PDF appears on Aon's candidate page as of 12 October 2026. Aon says every test begins with an introduction, a walkthrough and untimed example exercises.
Free trials come with every account. If it helps, a 14-Day Pass for 49 € removes the limit for two weeks.
