Which discipline is best described as designing systems with pulleys, gears, drives, and torque?

• A. Mechanical
• B. Civil
• C. Electrical
• D. Aerospace

Answer: (A)

Designing machines and their moving parts is the central focus here. Pulleys and belts, gears, drives, and torque are classic elements used to control motion and transfer power in mechanical systems. Mechanical engineering covers how these components interact to convert and transmit energy, control speeds, and produce the desired motion in machines. Civil engineering deals with structures and infrastructure, electrical engineering with circuits and signals, and aerospace engineering with aircraft and spacecraft systems. So, the best fit for systems built around moving parts like pulleys, gears, drives, and torque is mechanical engineering.
