How many forces and motion questions are on the Mechanical aptitude?

There is no single publisher to ask. “Mechanical aptitude test” names a category rather than a product: the two tests employers actually send are the Bennett Mechanical Comprehension Test, published by Pearson TalentLens as 55 items in 25 minutes, and the Wiesen Test of Mechanical Aptitude, published by Criteria Corp as 60 items in 30 minutes. Neither publisher breaks its test down by topic, so a page telling you how many gear questions to expect has invented the number and the test it belongs to. The 30-question run on this site is its own practice length and deals the types evenly.

Is this section timed?

Not on this page. These sets are for learning the type — each answer comes with an explanation straight away. When you want the clock, the full-length run is 30 questions in 15 minutes, which is 30 seconds a question.

Are these real questions from the test?

No. Every question here is original, written to the published format. The real item banks are confidential and nobody outside the publisher has them.

Mechanical aptitude forces and motion questions

Balance, turning force, friction, momentum and where a load actually goes.

A ladder leans against a wall. To make it less likely to slide out at the bottom, the base should be:

What this type asks

This is the half of the test that asks whether you can see forces in a still picture: which end of the plank tips, which way the crate slides, which rope carries more of the weight, what happens to the load when the crane arm swings out. Two ideas carry most of it. A thing balances when the turning effects on either side of the pivot match, which is why a small weight far out holds a big weight close in. And a thing stays where it is until something unbalanced acts on it, which is why the load on a braking truck keeps going. Neither publisher expects trade knowledge — the Wiesen’s items are written at a sixth-grade reading level — so the difficulty is entirely in reading the situation.

Now do it with the clock running.

30 questions in 15 minutes — 30 seconds each. That clock is this site's rather than any publisher's, because more than one publisher sells a test under this name and they are not the same length. Working under a clock is still the part untimed practice cannot teach.
