What Mechanical Comprehension Covers
Mechanical Comprehension (MC) tests how simple machines and physical forces work:
- Levers, pulleys, and inclined planes.
- Gears: direction and speed of connected gears.
- Pressure, force, and mechanical advantage.
10 Free Practice Questions
Two gears are touching. If the first gear turns clockwise, which way does the second gear turn?
(The interactive quiz loads here: 10 questions, instant feedback, explanations.)
How to Score Higher on Mechanical Comprehension
- Simple machines trade force for distance. Less effort means more distance moved.
- Gears that touch spin in opposite directions, and a smaller gear spins faster.
- Draw a quick sketch when a question describes a setup in words.
