7.1. Definition and Function of Actuators

Try these first

1. 1.

   Define an actuator in your own words.

   Hint

   Think about what an actuator does in a machine.

2. 2.

   What types of energy can actuators convert?

   Hint

   Remember the forms of energy mentioned.

3. 3.

   What is the primary function of an actuator?

   • To sense environment
   • To convert signals into motion
   • To store energy

   Hint

   Recall what actuators do in a system.

4. 4.

   True or False: Actuators can only produce linear motion.

   • True
   • False

   Hint

   Think about the types mentioned in the lesson.

5. 5.

   Consider a scenario where you need to lift a structure weighing 20,000 lbs. What type of actuator would you choose and why?

   Hint

   Recall the force capabilities discussed.

6. 6.

   Design a simple automated system for opening and closing a valve using actuators. What types would you use and how would they function together?

   Hint

   Consider both speed and energy type for operation.
