Mechanical Comprehension practice test
How simple machines and mechanical systems behave.
Mechanical Comprehension asks about how simple machines and mechanical systems behave: levers, pulleys, gears, springs, hydraulics and the forces that act on them. The questions are conceptual — they test whether you understand the principle, not whether you can do a long calculation. A question might ask which way a gear turns, what a lever does, or how a hydraulic system multiplies force. The bank here covers the concepts most often tested, each question original and written for this site, with a one-line explanation of the correct answer.
