Mechanical Engineering topic-wise MCQs
All 8 topics of Mechanical Engineering, in syllabus order with the depth of the bank behind each one. Tap a topic to practise it on its own.
No solved Mechanical Engineering papers have been counted yet, so the share column is each topic's share of the Mechanical Engineering bank rather than of a real paper. It tells you where the practice material is deepest, which is not the same as where the marks are.

Exams that test Mechanical Engineering
Every exam on TestUstad that examines Mechanical Engineering, and how much of each paper it is worth. The weightage is what decides how much of your preparation Mechanical Engineering deserves: at 80 of 100 MCQs it is 80% of the Assistant Engineer Mechanical Test paper on its own.
Mechanical Engineering in government job tests
| Exam | Mechanical Engineering MCQs | Share of paper |
|---|---|---|
| Assistant Engineer Mechanical Test Mechanical Engineering MCQs Assistant Engineer Mechanical Test. Conducted by Public Service Commissions. | 80 | 80% |
| Sub Engineer Mechanical Test Mechanical Engineering MCQs Sub Engineer Mechanical Test. Conducted by Public Service Commissions. | 70 | 70% |
How to prepare Mechanical Engineering for your test
Work one topic at a time, not the whole subject. Reading Mechanical Engineering end to end feels productive and is the slowest way to raise a score. Pick a single topic, solve its MCQs until you are consistently above 80 percent, and only then move on. There are 8 to get through.
Read the explanation on every question you get wrong. This is the whole reason to practise online rather than from an answer key. A wrong answer is only useful if it tells you which fact you were missing, so every Mechanical Engineering MCQ here carries a written explanation and no question can be published without one.
Finish with mixed, timed practice. Recalling a fact under the clock is a different skill from recognising it while you revise, and it is the one the paper actually tests. Once several topics feel solid, sit a timed test that mixes them rather than practising one topic at a time.
Mechanical Engineering preparation by exam
Each exam hub adds the things that are true of that paper alone: its pattern, its subject weightage, its solved past papers and a study plan built around its date.
Mechanical Engineering MCQs: frequently asked questions
Are these Mechanical Engineering MCQs free?
Yes. Every Mechanical Engineering MCQ on TestUstad is free to read and practise, with unlimited attempts, no daily limit and no account required. There is no trial that expires and no paywall on the question bank. Only full-length mock tests and long-term progress tracking are paid.
Do the Mechanical Engineering MCQs come with answers and explanations?
Yes. Every Mechanical Engineering question shows the correct answer and a written explanation of why that option is correct, not just an answer key letter. A question cannot be published on TestUstad without an explanation.
Are the Mechanical Engineering MCQs chapter-wise?
Yes. The Mechanical Engineering MCQs are split into 8 chapters so you can practise one chapter at a time instead of working through the whole subject. You can also practise every Mechanical Engineering question together from the "All MCQs" page.
Which exams do these Mechanical Engineering MCQs help with?
The same Mechanical Engineering bank is used for every exam that tests Mechanical Engineering, including Assistant Engineer Mechanical Test, Sub Engineer Mechanical Test. A Mechanical Engineering question does not change between exams, so practising here prepares you for all of them at once.
Are these Mechanical Engineering MCQs only for Assistant Engineer Mechanical Test?
No. Assistant Engineer Mechanical Test is the paper that carries the most Mechanical Engineering, at 80 of its 100 MCQs, but the same Mechanical Engineering bank is drawn by every other exam that examines the subject, including Sub Engineer Mechanical Test. Nothing here is written for one paper: a Mechanical Engineering fact is the same fact whichever exam asks it, so you can prepare for all of them from this one page.
How should I prepare Mechanical Engineering for a test?
Work one chapter at a time rather than reading the whole subject end to end. Solve that chapter's MCQs until you are consistently above 80 percent, read the explanation on every question you get wrong, and move on only then. There are 8 Mechanical Engineering chapters to get through. Once several chapters feel solid, sit a timed test that mixes them, because recalling a fact under the clock is a different skill from recognising it while you revise.
Do I need to sign up to practise Mechanical Engineering MCQs?
No. You can practise Mechanical Engineering MCQs on TestUstad without creating an account, without giving an email address and without a card. An account only saves your history and progress across sessions.
