1. In a mechatronic production system, which component primarily
converts electrical energy into mechanical motion?
A. Capacitor
B. Thermistor
C. Actuator
D. Rectifier
Actuators are responsible for converting electrical, hydraulic, or pneumatic
energy into physical movement within mechatronic systems. Common
examples include electric motors and pneumatic cylinders.
2. Which sensor is most commonly used to detect rotational position in
servo systems?
,A. Load cell
B. Thermocouple
C. Flow meter
D. Encoder
Encoders provide feedback regarding rotational position, speed, and
direction, making them essential in servo-controlled systems requiring
precise motion control.
3. Ohm’s Law states that voltage equals:
A. Resistance divided by current
B. Current squared times resistance
C. Current multiplied by resistance
D. Power divided by current
Ohm’s Law is expressed as V = IR, where voltage equals current multiplied
by resistance. It is fundamental in electrical circuit analysis.
4. Which controller action reduces steady-state error in a PID control
system?
A. Derivative action
B. Feedforward action
C. Proportional gain reduction
D. Integral action
,Integral action accumulates error over time and adjusts the output until
the steady-state error is minimized or eliminated.
5. What is the primary function of a programmable logic controller (PLC)?
A. Store hydraulic fluid
B. Amplify pneumatic pressure
C. Automate industrial control processes
D. Measure thermal conductivity
PLCs are industrial digital controllers designed to automate machinery and
processes through programmed logic operations.
6. Which type of motor is commonly used for precise positioning
applications?
A. Induction motor
B. Universal motor
C. Stepper motor
D. Synchronous generator
Stepper motors move in discrete steps, allowing accurate position control
without requiring continuous feedback in many applications.
7. In pneumatic systems, compressed air is typically stored in a:
, A. Transformer
B. Capacitor bank
C. Heat exchanger
D. Receiver tank
Receiver tanks store compressed air and help stabilize pressure
fluctuations within pneumatic systems.
8. Which communication protocol is widely used in industrial automation
networks?
A. HDMI
B. SATA
C. Bluetooth Classic only
D. Modbus
Modbus is a widely adopted industrial communication protocol used for
transmitting information between automation devices.
9. A strain gauge is primarily used to measure:
A. Temperature
B. Velocity
C. Pressure only
D. Mechanical deformation
