View Answer
Explanation: The process which refers to the usage of machinery to assist the human workers in performing a task is known as mechanization. It is to be noted that human workers still required assisting the machinery in performing the task.
3. Which of the following is not the basic component of an automated system?
a) Power
b) Storage System
c) Control System
d) Program of Instructions
View Answer
Explanation: Storage system is not a basic component of an automated system. Power, Control System and Program of Instructions are the basic components of an automated system.
4. Which is required to drive the process as well as controls in an automated system?
a) Guides Wire
b) Power
c) Wheel
d) Pallet
View Answer
Explanation: The important element of an automated system is power. In order drive the process as well as controls in an automated system, power is required. Guided wire, Wheel and pallet were not typically required to drive the process as well as controls in an automated system.
5. Which is the source of power in an automated system?
a) Hydrogen
b) Diesel
c) Coal
d) Electricity
View Answer
Explanation: The source of power in an automated system is electricity. Electricity is established by the potential difference between the ends of system by the exchange of ions.
6. Electric Power cannot be converted into other forms of work.
a) False
b) True
View Answer
Explanation: Electric Power can be converted into other forms of work. It can be converted into other forms such as mechanical, pneumatic, thermal and magnetic energy.
7. Which is termed as the manufacturing operation that is performed on a work unit?
a) Load
b) Product
c) Unit
d) Process
View Answer
Explanation: Manufacturing operation that is performed on a work unit is termed as process. In an automated system, process is cyclical. When the process ends, the same will be started periodically.
8. Which form of power is required for casting?
a) Mechanical
b) Hydraulic
c) Thermal
d) Pneumatic
View Answer
Explanation: For casting process, thermal form of power is required. It is a process where the metal is melted and the molten metal will be poured into the cavity in order to gain the shape of the cavity.
9. Which form of power is required for electric discharge machining?
a) Mechanical
b) Hydraulic
c) Thermal
d) Mechanical
View Answer
Explanation: For electric discharge machining process, electric form of power is required. It is a process where the removal of metal is done by discrete electrical discharges between the electrodes.
10. Which form of power is required for forging?
a) Mechanical
b) Hydraulic
c) Thermal
d) Mechanical
View Answer
Explanation: For forging process, mechanical form of power is required. It is a process where the solidified metal at high temperatures will be applied heavy blow in order to strengthen it.
11. Which form of power is required for injection molding?
a) Pneumatic
b) Hydraulic
c) Electricity
d) Thermo Mechanical
View Answer
Explanation: For injection molding process, thermo mechanical form of power is required. It is a process where the molten plastic particles will be poured into the die in order to retain the shape of the die.
12. Which unit performs the control calculations execute the instructions?
a) Operator
b) Storage Unit
c) Power Unit
d) Control Unit
View Answer
Explanation: In an automated system, Control Unit performs the control calculations execute the instructions. In order to perform this function, additional power will be transmitted to this system.
13. Which devices are used to transmit the commands sent by the control unit?
a) Hydraulic Devices
b) Modular Devices
c) Radiant Devices
d) Electromechanical devices
View Answer
Explanation: In order to transmit the commands sent by the control unit, electromechanical devices will be used in an automated system. These devices require high accuracy and precision to perform this function.
14. How are the commands generally transmitted in a control unit?
a) Hyper Signals
b) High Voltage Signals
c) Null Signals
d) Low Voltage Signals
View Answer
Explanation: In order to transmit the commands sent by the control unit, low voltage control signals will be generated. For this purpose, amplifying devices will be used in order to amplify the signal to make it to the actuators.
15. Which are used as an input to the control algorithms?
a) Voltage
b) Guided Wire
c) Resistor
d) Data
View Answer
Explanation: In an automated system, data serves as an input to the control algorithms. It is usually collected from the previous processes and recorded. While optimizing the existing system, these data will be fed to the control algorithms.
