This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Actuators Types”.
1. Which of the following consists of a movable plunger inside a stationary wire coil?
a) Inverter
b) Moderator
c) Regulator
d) Solenoid
View Answer
Explanation: The component which consists of a movable plunger inside a stationary wire coil is known as solenoid. It is one of the electrical actuators commonly used in an industrial control other than motors.
2. Which of the following can be used to open or close an electrical contact by means of magnetic field?
a) Modulator Relay
b) Electromechanical Relay
c) Inverter
d) Exciter
View Answer
Explanation: The type of relay which can be used to open or close an electrical contact by means of magnetic field is known as electromechanical relay. It is an ON-OFF electrical switch consisting of a stationary coil and a moveable arm.
3. What will be typical pressure level used in a hydraulic system?
a) 1 MPa
b) 20 MPa
c) 100 MPa
d) 0.2 MPa
View Answer
Explanation: The typical pressure level which will be used in a hydraulic system is about 20 MPa. It is to be noted that this pressure will be applied to the working liquid. 1 MPa, 100 MPa and 0.2 MPa are not the typical pressure level used in a hydraulic system.
4. What will be the typical pressure level used in a pneumatic system?
a) 20 MPa
b) 0.01 MPa
c) 0.7 MPa
d) 70 MPa
View Answer
Explanation: The typical pressure level which will be used in a pneumatic system is about 0.7MPa. In this system, the working air will be compressed to such pressure. 20 MPa, 0.01 MPa and 0 MPa are not the typical pressure level used in a pneumatic system.
5. The actual speed of pneumatic system is very low.
a) False
b) True
View Answer
Explanation: The actual speed of pneumatic system is high when compared to hydraulic system where the typical actual speed will be low. The usage of air as a working medium in a typical pneumatic system accelerates the process to achieve at higher speed.
