This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Actuators”.
1. Which of the following is a hardware device that converts a controller command into a change in physical system?
a) Regulator
b) Radiator
c) Actuator
d) Moderator
View Answer
Explanation: The device which converts a controller command into a change in physical system is known as actuator. The change in the physical system is timely based and will be pre programmed if necessary.
2. Which is required to strengthen the signal sufficiently to drive the actuator?
a) Modulator
b) Regulator
c) Amplifier
d) Abstractor
View Answer
Explanation: The device which is used to strengthen the signal sufficiently to drive the actuator is known as amplifier. Modulator, Regulator and Abstractor were not typically used to strengthen the signal sufficiently to drive the actuator.
3. Which type of actuators are the most commonly used?
a) Thermal
b) Electric
c) Hydraulic
d) Pneumatic
View Answer
Explanation: The type of actuators which is more commonly used is known as electric actuators. They include motors, solenoids and electromechanical relays. Thermal, Electric and Hydraulic were not the most typically used actuators.
4. Rotational electric actuators are used for linear displacement applications.
a) False
b) True
View Answer
Explanation: Rotational electric actuators are used for angular displacement applications. Linear electric actuators are commonly used for linear displacement applications.
5. Which type of actuators use hydraulic fluid to amplify the controller command signal?
a) Magnetic
b) Pneumatic
c) Electric
d) Hydraulic
View Answer
Explanation: The type of actuators which use hydraulic fluid to amplify the controller command signal is known as hydraulic actuators. It is used in applications where large force has to be applied.
6. Which of the following actuators use compressed air to amplify the signal?
a) Magnetic
b) Pneumatic
c) Electric
d) Hydraulic
View Answer
Explanation: The actuators which use compressed air to amplify the controller signal are known as pneumatic actuators. Magnetic, Electric and Hydraulic were not the typically used actuators which use compressed air to amplify the signal
