Mechanical & Physical ReasoningGears, levers, pulleys and ramps — physical intuition tested in words, verified by physics.
Twenty multiple-choice items on gear ratios and direction, lever classes, pulleys and block-and-tackle, hydraulics, pressure, springs, projectiles, ramps, circuits, belts and counterweights, all described in text. Twenty minutes; scored on Spatial & Mechanical Reasoning with every quantity explained.
In brief
Mechanical & Physical Reasoning is an online assessment in AssessAll's Aptitude Catalogue line taking about 20 minutes. It measures spatial & mechanical reasoning. It is built for candidates for technician, maintenance, field-service and production roles with a technical aptitude round. Scoring is evidence-keyed, and the full report is available immediately after submission, priced in INR and USD.

The classic technical screen, with every number checked by computation
One item gives you two meshed gears with different tooth counts, turns the driver twice and asks how far the driven gear turns. Another describes a block-and-tackle with several supporting rope segments lifting a stated load and asks for the pull needed. A third has a ramp of given length and height and a load to push up it. Others ask which surface pairing gives the least friction, where a projectile momentarily stops, how pressure changes with depth, and what happens to two springs joined end to end. Everything is described in words, so it runs on any device and needs no diagrams.
The 20-item bank is original and follows international mechanical-reasoning conventions — moments, mechanical advantage, transmission — and every key has been verified by computation from the underlying physics. Distractors are the outputs of the standard wrong models: the gear ratio applied upside down, the mechanical advantage counted from the wrong number of rope segments, the ramp force taken from weight alone. The bank is not affiliated with any third-party instrument, and no formula sheet is provided or needed beyond a working intuition for how machines behave.
One competency, Spatial & Mechanical Reasoning, is scored and banded with a coaching interpretation, and the report gives it depth a single number cannot: all 20 items are reviewed with the correct answer and the physical principle that produces it, so a candidate sees whether misses cluster on rotational systems, force multiplication or fluids. The growth plan is built from that pattern, which for a maintenance or field applicant is a study list before the next technical round.
What you walk away with
Your 0–100 score is placed in one of four bands — Emerging, Developing, Strong or Exceptional — with a coaching interpretation of what that band means for technical, maintenance and manufacturing work. Hiring teams get a consistent line across applicants without a pass mark.
Every item comes back with your choice, the key and the principle behind it: why the driven gear turns fewer times, why more rope segments mean less pull, why the ramp divides the force by its length-to-height ratio. It is a compact revision course in applied mechanics.
Because the review covers rotation, levers, pulleys, hydraulics, springs, ramps and circuits, a candidate can see which family of machine they misjudge. Strengths and development areas are named from your own responses, not a generic list.
The plan turns your weakest item families into practical preparation — the concepts to revisit and the kind of problems to rehearse — sized for someone with a field, maintenance or production interview coming up rather than a physics course.

One number, one band, and a two-sentence summary of what the band means for you — then the breakdown that explains it.
Assembled from your lowest competencies, in order — not a generic checklist.

Frequently asked questions
Twenty multiple-choice items on how machines and physical systems behave: gear ratios and direction, the three lever classes, fixed pulleys versus block-and-tackle, hydraulics, pressure and depth, springs in series, projectile turning points, ramps, simple circuits, belts and counterweights. It scores one competency, Spatial & Mechanical Reasoning, and is the standard screen for technical, maintenance, field-service and manufacturing roles.
No. The items are built on intuition for how machines work — more teeth means fewer turns, more rope segments mean less pull, a longer ramp means less force — and the numbers are chosen to be workable in your head. Every key has been verified by computation, and the distractors are the standard wrong models, so a guess that feels right often is not. The item review then states the principle, so you learn each one you missed.
Twenty minutes for 20 items, on any device, with no diagrams required. The report arrives immediately: an overall 0–100 score with a band and coaching interpretation, a personalised narrative, strengths and development areas grouped by mechanism, a growth plan and a review of all 20 items with the physical principle behind each key. Everything is included; there is nothing further to unlock.
Hiring teams set a band threshold for technician and trainee intakes and use the item review to probe a candidate's reasoning on a mechanism they missed. Candidates use the review as targeted revision before a plant or field interview, work the growth plan and retake to confirm the band has moved. There is no pass mark, so the report works equally as a development baseline for existing staff.
Yes. Physics is the same everywhere, the items use metric units and neutral settings, and the format follows international mechanical-reasoning conventions used in technical hiring worldwide. The report is written in plain international English. The test is priced in INR and USD, with the live price for each shown on this page, so a candidate or employer anywhere pays in the currency that suits them.
Numerical, verbal, logical, abstract, spatial, data and workplace-judgment banks — each an original item bank with every rule stated in the explanation, scored per competency and reported with a banded profile and a growth plan. Sit one, or build a battery from several.

What should you do after taking the Mechanical & Physical Reasoning?
Use the report as a baseline, not a verdict. Turn it into an individual development plan on Jobulary, with three objectives for the next 90 days; practise the gaps with the Critical Thinking & Decision Making Kit for the AI Era on Bodhih.org; and, for a team, run the Critical Thinking Training for Employees with Bodhih Training. Then take the Mechanical & Physical Reasoning again to see what moved.
