✍️ Sample MECHANICAL APTITUDE Questions & Answers
1. For a simply supported beam carrying a single concentrated load at its midpoint, maximum bending moment occurs at:
For a simply supported beam with a central point load, the bending moment diagram forms a triangle with its peak value at the midpoint load location.
2. A gear with 60 teeth drives a gear with 20 teeth. What is the gear ratio?
The gear ratio is the number of teeth on the driving gear divided by the number on the driven gear: 60/20 = 3:1. The driven gear rotates 3 times for every 1 rotation of the driving gear, providing speed increase but torque reduction.
3. What is the difference between ferrous and non-ferrous metals?
Ferrous metals contain iron as their primary component (steel, cast iron, wrought iron), while non-ferrous metals do not contain significant iron (aluminum, copper, brass, titanium). Ferrous metals are typically magnetic and susceptible to rust.
4. Viscosity is a measure of a fluid's:
Viscosity is defined as the measure of a fluid's internal friction or its resistance to flow. A fluid with high viscosity, like honey, flows slowly because of the strong internal friction between its layers. A fluid with low viscosity, like water, flows easily.
5. Which measuring instrument is best suited for checking the inside diameter of a cylinder bore?
A telescoping gauge expands to contact the inner walls of a bore, then is locked and measured with a micrometer for precise readings.
6. What is the purpose of a worm gear?
A worm gear provides high gear reduction in a compact space and is typically self-locking — the worm can drive the gear, but the gear cannot drive the worm. This makes worm gears ideal for applications requiring high torque and a built-in braking effect.

What Practice Test Geeks adds beyond an AI chat for Mechanical Aptitude
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length Mechanical Aptitude mock exam — 60 questions in 60 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed Mechanical Aptitude question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable Mechanical Aptitude cheat sheet you can print or save as a PDF.
- Mechanical Aptitude flashcards built from the same question bank.
- Free Mechanical Aptitude practice tests with the correct answer shown after each question.
