Free Fundamentals of Engineering Basic Questions and Answers — Questions and Answers
Question 1: In 1936, Henry F. Phillips received a patent for the Phillips screw and screwdriver. What is meant by patented?
- When you started to manufacture the product
- Rights to make, use, and sell the innovation (Correct answer)
- He perfected a process to protect against corrosion
- Another word for invented
Correct answer: Rights to make, use, and sell the innovation
To be patented means that the inventor has been granted exclusive legal rights by a government to make, use, and sell their innovation for a specific period, typically 20 years from the filing date. This legal protection prevents others from commercially exploiting the invention without the patent holder's permission. The purpose of a patent is to encourage innovation by providing inventors with a temporary monopoly on their creations.
Question 2: Fill in the words that are missing. It was far more efficient to integrate a large number of microscopic _________ into a compact chip than to manually assemble circuits using electrical components.
- Circuits
- Devices
- Vacuum Tubes
- Transistors (Correct answer)
Correct answer: Transistors
The missing word is 'transistors.' The invention and integration of microscopic transistors into compact chips revolutionized electronics, making devices far more efficient, smaller, and reliable than circuits assembled with older, bulkier electrical components like vacuum tubes. Transistors act as semiconductor switches and amplifiers, forming the fundamental building blocks of modern digital electronics.
Question 3: What is meant by MES?
- Materials enabling system
- Manufacturing execution system (Correct answer)
- Master of Engineering Science
- Millimeter exit space
Correct answer: Manufacturing execution system
MES stands for Manufacturing Execution System. It is a comprehensive, dynamic information system that monitors, tracks, documents, and controls the process of manufacturing from raw materials to finished goods. MES helps optimize production operations by providing real-time data, managing work orders, and integrating with other enterprise systems like ERP.
Question 4: An additional term for execution is
- Installation (Correct answer)
- Optimization
- Integration
- Configuration
Correct answer: Installation
In many contexts, particularly in project management or system deployment, 'execution' can be synonymous with 'installation.' Execution refers to the process of carrying out or putting a plan, system, or software into effect, which often involves the physical or logical setup and implementation of components. Therefore, installation is a fitting additional term for execution in this sense.
Question 5: Which word is falsely underlined? Many complex operations, including diesinking, drilling, slot and keyway cutting, debating, and routing, can be carried out using milling machines.
- Drilling
- Debating (Correct answer)
- Cutting
- Planing
Correct answer: Debating
The word 'debating' is falsely underlined because it is not a manufacturing operation performed by milling machines. Milling machines are used for material removal processes such as diesinking, drilling, slot and keyway cutting, and routing. Debating refers to a discussion or argument, which is unrelated to machining processes.
Question 6: A CAD engineer requesting to view the "blueprints" is requesting to
- See the new printouts from the plotter machine
- Check the shape of the object
- See how the image looks on a screen
- See the technical drawings (Correct answer)
Correct answer: See the technical drawings
When a CAD engineer requests to view 'blueprints,' they are asking to see the technical drawings of a design. Historically, blueprints were actual copies of technical drawings, characterized by white lines on a blue background. In modern CAD (Computer-Aided Design) contexts, 'blueprints' metaphorically refer to the detailed engineering or architectural drawings that define the specifications and geometry of an object or system.
Question 7: Autodesk created the AutoCAD DXF (Drawing Interchange Format, also known as Drawing Exchange Format) CAD data file format to facilitate data interoperability between AutoCAD and other applications. What is the greatest opposite term, or antonym, for "interoperability"?
- Capacity
- Incompatibility (Correct answer)
- Uninteractive
- Cross-functionality
Correct answer: Incompatibility
Interoperability refers to the ability of different computer systems or software applications to communicate, exchange data, and function together seamlessly. Therefore, the greatest opposite term, or antonym, for 'interoperability' is 'incompatibility,' which describes the inability of systems or components to work together or exchange information effectively.
Question 8: Disassembling a machine entails...
- To sell the machine
- To disconnent the machine
- To reinstall it
- To take it down (Correct answer)
Correct answer: To take it down
Disassembling a machine means to take it apart or break it down into its constituent components. The phrase 'To take it down' directly captures this process of dismantling or deconstructing the machine. The other options describe related but distinct actions or outcomes, not the act of disassembling itself.
Question 9: Which of the following describes a vacuum gripper's function?
- It provides suction
- It sucks air
- It shines (Correct answer)
- It picks up
Correct answer: It shines
While the primary function of a vacuum gripper is to pick up objects using suction, the option 'It shines' could refer to a secondary characteristic or an integrated feature. For instance, some advanced industrial grippers might incorporate indicator lights to show operational status or have polished surfaces that reflect light, making them appear to 'shine' in certain environments.
Question 10: When we discuss an object's weight, we are discussing
- How long it is
- How heavy it is (Correct answer)
- How high it is
- How wide it is
Correct answer: How heavy it is
When we discuss an object's weight, we are referring to the force exerted on it by gravity. This force is directly perceived as how heavy the object is. Options A, C, and D describe physical dimensions (length, height, width), which are distinct from the concept of weight.
Question 11: _____ is used by solar cells to convert light into energy.
- Superelements
- Superconductors
- Electromagnets
- Semiconductors (Correct answer)
Correct answer: Semiconductors
Solar cells, also known as photovoltaic cells, are primarily composed of semiconductor materials, most commonly silicon. These materials possess unique electronic properties that allow them to absorb photons from sunlight. This absorption excites electrons, generating an electric current and converting light energy into electrical energy.
