Mechanical Control Systems Quiz

What is the main difference between mechanical and electrical control systems?

• Mechanical systems are powered by electricity.

• Electrical systems use levers and pulleys.

• Electrical systems are more efficient than mechanical systems.

• Mechanical systems use moving parts, while electrical systems do not.
